IMIS-2020 Keynote Talks

Semantics, Patterns and Compiler Techniques for Portable App Development in Multiple Cloud and Big Data Platforms Beniamino Di Martino University of Campania “Luigi Vanvitelli”, Aversa, Italy

Abstract. Cloud vendor lock-in and interoperability gaps arise (among many reasons) when semantics of resources and services and of application programming interfaces is not shared. The same issue arises with big data platforms: different programming, deployment and execution models, many different Machine Learning Libraries and related APIs. Standards and techniques borrowed from SOA and semantic Web services areas might help in gaining shared, machine readable description of cloud and big data offerings (resources, services at platform and application level, libraries and their API groundings), thus allowing automatic discovery, matchmaking, and thus selection, brokering, interoperability end composition of cloud services among multiple clouds, and seamless programming of analytics on multiple big data platforms. This talk will illustrate in particular the outcomes of the EU-funded projects MOSAIC (http://www.mosaic-cloud.eu) and TOREADOR (http://www.toreador-project.eu).

Distributed Systems of the Day for Efficient Digital Data Exchange and Sharing: A System Transition from Peer-to-Peer to Cloud-Fog-Edge Computing Shinji Sugawara Chiba Institute of Technology, Chiba, Japan

Abstract. With the recent increase of bandwidth for communication networks, the major improvement of computing processors and the spread of cloud computing, the exchanges or sharing of various types and huge amount of data or digital contents has become very active among a great many users on a large-scale network represented by the Internet. For this, various distributed systems have been used so far and major system architecture has been continuously changing according to the functions and purposes required at each time period. In this talk, we describe the historical changes and classifications of distributed systems used for searching, exchanging, storing and sharing data deployed on networks and their respective advantages. We introduce examples of actually implemented systems. Furthermore, we discuss the possibility of future development of distributed systems for data sharing.

Abstract. The Wireless Mesh Networks (WMNs) are becoming an important networking infrastructure because they have many advantages such as low cost and increased high speed wireless Internet connectivity. In our previous work, we implemented a simulation system considering Particle Swarm Optimization (PSO), Simulated Annealing (SA) and Distributed Genetic Algorithm (DGA), called WMN-PSOSA-DGA. In this paper, we present the performance of WMNs using WMN-PSOSADGA simulation system considering Linearly Decreasing Vmax Method (LDVM) and Rational Decrement of Vmax Method (RDVM). Simulation results show that a good performance is achieved for RDVM compared with the case of LDVM.

Introduction

The wireless networks and devices are becoming increasingly popular and they provide users access to information and communication anytime and anywhere [1,3,11,12,14,18,21,22]. Wireless Mesh Networks (WMNs) are gaining a lot of attention because of their low cost nature that makes them attractive for c Springer Nature Switzerland AG 2021  L. Barolli et al.

providing wireless Internet connectivity. A WMN is dynamically self-organized and self-configured, with the nodes in the network automatically establishing and maintaining mesh connectivity among them-selves (creating, in effect, an ad hoc network). This feature brings many advantages to WMNs such as low up-front cost, easy network maintenance, robustness and reliable service coverage [2]. Mesh node placement in WMN can be seen as a family of problems, which are shown (through graph theoretic approaches or placement problems, e.g. [9,16]) to be computationally hard to solve for most of the formulations [34]. We consider the version of the mesh router nodes placement problem in which we are given a grid area where to deploy a number of mesh router nodes and a number of mesh client nodes of fixed positions (of an arbitrary distribution) in the grid area. The objective is to find a location assignment for the mesh routers to the cells of the grid area that maximizes the network connectivity and client coverage. Network connectivity is measured by Size of Giant Component (SGC) of the resulting WMN graph, while the user coverage is simply the number of mesh client nodes that fall within the radio coverage of at least one mesh router node and is measured by Number of Covered Mesh Clients (NCMC). Node placement problems are known to be computationally hard to solve [13,35]. In previous works, some intelligent algorithms have been investigated for node placement problem [4,10,17,19,20,26,27,36]. In [25], we implemented a Particle Swarm Optimization (PSO) and Simulated Annealing (SA) based simulation system, called WMN-PSOSA. Also, we implemented another simulation system based on Genetic Algorithm (GA), called WMN-GA [4,15], for solving node placement problem in WMNs. Then, we designed a hybrid intelligent system based on PSO, SA and DGA, called WMN-PSOSA-DGA [24]. In this paper, we evaluate the performance of WMNs using WMN-PSOSADGA simulation system considering Linearly Decreasing Vmax Method (LDVM) and Rational Decrement of Vmax Method (RDVM). The rest of the paper is organized as follows. We present our designed and implemented hybrid simulation system in Sect. 2. The simulation results are given in Sect. 3. Finally, we give conclusions and future work in Sect. 4.

Proposed and Implemented Simulation System

Distributed Genetic Algorithm (DGA) has been focused from various fields of science. DGA has shown their usefulness for the resolution of many computationally hard combinatorial optimization problems. Also, Particle Swarm Optimization (PSO) and Simulated Annealing (SA) are good approachs for solving NP-hard problems. 2.1

Velocities and Positions of Particles

WMN-PSOSA-DGA decide the velocity of particles by a random process considering the area size. For instance, when the area size is W × H, the velocity

√ √ is decided randomly from − W 2 + H 2 to W 2 + H 2 . Each particle’s velocities are updated by simple rule [23]. For SA mechanism, next positions of each particle are used for neighbor solution s . The fitness function f gives points to the current solution s. If f (s ) is larger than f (s), the s is better than s so the s is updated to s . However, if f (s) is not larger  than f (s), the s may be updated by using the probability of 

(s) . Where T is called the “Temperature value” which is decreased exp f (s )−f T with the computation so that the probability to update will be decreased. This mechanism of SA is called a cooling schedule so that the next Temperature value of computation is calculated as Tn+1 = α × Tn . In this paper, we set the starting temperature, ending temperature and number of iterations, we calculate α as

 α=

1.0/number of iterations .

It should be noted that the positions are not updated but the velocities are updated in the case of the solution s is not updated. 2.2

Routers Replacement Methods

A mesh router has x, y positions and velocity. Mesh routers are moved based on velocities. There are many router replacement methods. In this paper, we use LDVM and RDVM. Constriction Method (CM) CM is a method which PSO parameters are set to a week stable region (ω = 0.729, C1 = C2 = 1.4955) based on analysis of PSO by M. Clerc et al. [5,8,30]. Random Inertia Weight Method (RIWM) In RIWM, the ω parameter is changing randomly from 0.5 to 1.0. The C1 and C2 are kept 2.0. The ω can be estimated by the week stable region. The average of ω is 0.75 [7,28,32]. Linearly Decreasing Inertia Weight Method (LDIWM) In LDIWM, C1 and C2 are set to 2.0, constantly. On the other hand, the ω parameter is changed linearly from unstable region (ω = 0.9) to stable region (ω = 0.4) with increasing of iterations of computations [6,33]. Linearly Decreasing Vmax Method (LDVM) In LDVM, PSO parameters are set to unstable region (ω = 0.9, C1 = C2 = 2.0). A value of Vmax which is maximum velocity of particles is considered. With increasing of iteration of computations, the Vmax is kept decreasing linearly [7,29,31]. Rational Decrement of Vmax Method (RDVM) In RDVM, PSO parameters are set to unstable region (ω = 0.9, C1 = C2 = 2.0). The Vmax is kept decreasing with the increasing of iterations as Vmax (x) =

DGA Operations

Population of individuals: Unlike local search techniques that construct a path in the solution space jumping from one solution to another one through local perturbations, DGA use a population of individuals giving thus the search a larger scope and chances to find better solutions. This feature is also known as “exploration” process in difference to “exploitation” process of local search methods. Selection: The selection of individuals to be crossed is another important aspect in DGA as it impacts on the convergence of the algorithm. Several selection schemes have been proposed in the literature for selection operators trying to cope with premature convergence of DGA. There are many selection methods in GA. In our system, we implement 2 selection methods: Random method and Roulette wheel method.

Crossover operators: Use of crossover operators is one of the most important characteristics. Crossover operator is the means of DGA to transmit best genetic features of parents to offsprings during generations of the evolution process. Many methods for crossover operators have been proposed such as Blend Crossover (BLX-α), Unimodal Normal Distribution Crossover (UNDX), Simplex Crossover (SPX). Mutation operators: These operators intend to improve the individuals of a population by small local perturbations. They aim to provide a component of randomness in the neighborhood of the individuals of the population. In our system, we implemented two mutation methods: uniformly random mutation and boundary mutation. Escaping from local optimal: GA itself has the ability to avoid falling prematurely into local optimal and can eventually escape from them during the search process. DGA has one more mechanism to escape from local optimal by considering some islands. Each island computes GA for optimizing and they migrate its gene to provide the ability to avoid from local optimal. Convergence: The convergence of the algorithm is the mechanism of DGA to reach to good solutions. A premature convergence of the algorithm would cause that all individuals of the population be similar in their genetic features and thus the search would result ineffective and the algorithm getting stuck into local optimal. Maintaining the diversity of the population is therefore very important to this family of evolutionary algorithms. In following, we present fitness function, migration function, particle pattern and gene coding. 2.4

Fitness and Migration Functions

The determination of an appropriate fitness function, together with the chromosome encoding are crucial to the performance. Therefore, one of most important thing is to decide the determination of an appropriate objective function and its encoding. In our case, each particle-pattern and gene has an own fitness value which is comparable and compares it with other fitness value in order to share information of global solution. The fitness function follows a hierarchical approach in which the main objective is to maximize the SGC in WMN. Thus, the fitness function of this scenario is defined as Fitness = 0.7 × SGC(xij , y ij ) + 0.3 × NCMC(xij , y ij ). Our implemented simulation system uses Migration function as shown in Fig. 1. The Migration function swaps solutions between PSOSA part and DGA part. 2.5

Particle-Pattern and Gene Coding

In order to swap solutions, we design particle-patterns and gene coding carefully. A particle is a mesh router. Each particle has position in the considered area

and velocities. A fitness value of a particle-pattern is computed by combination of mesh routers and mesh clients positions. In other words, each particle-pattern is a solution as shown is Fig. 2. A gene describes a WMN. Each individual has its own combination of mesh nodes. In other words, each individual has a fitness value. Therefore, the combination of mesh nodes is a solution. Table 1.

Simulation Results

In this section, we show simulation results using WMN-PSOSA-DGA system. In this work, we analyze the performance evaluation of WMNs considering LDVM and RDVM router replacement methods. The number of mesh routers is considered 16 and the number of mesh clients 48. We conducted simulations 10 times, in order to avoid the effect of randomness and create a general view of results. We show the parameter setting for WMN-PSOSA-DGA in Table 1. We show simulation results in Fig. 3 and Fig. 4. We see that for SGC, the performance of LDVM and RDVM are almost the same, but for RDVM the convergence is faster. While for NCMC, the RDVM performs better than LDVM.

Conclusions

In this work, we evaluated the performance of WMNs using a hybrid simulation system based on PSO, SA and DGA (called WMN-PSOSA-DGA) considering LDVM and RDVM router replacement methods. Simulation results show that the performance is better for RDVM compared with the case of LDVM. In our future work, we would like to evaluate the performance of the proposed system for different parameters and patterns.

Abstract. In this work, we implement two Fuzzy-Based Systems: Node Elimination System (NES) and Node Selection System (NSS) for IoT node elimination and selection in OppNets. We use three input parameters for NES: Node’s Distance to Event (NDE), Node’s Battery Level (NBL), Node’s Free Buffer Space (NFBS) and four input parameters for NSS: Node’s Number of Past Encounters (NNPE), Node’s Unique Encounters (NUE), Node Inter Contact Time (NICT), Node Contact Duration (NCD). The output parameter is IoT Node Selection Possibility (NSP). The results show that the proposed systems make a proper elimination and selection decision for IoT nodes in OppNets.

Introduction

Communication systems are becoming increasingly complex, involving thousands of heterogeneous nodes with diverse capabilities and various networking technologies interconnected with the aim to provide users with ubiquitous access to information and advanced services at a high quality level, in a cost efficient manner, any time, any place, and in line with the always best connectivity principle. The Opportunistic Networks (OppNets) can provide an alternative way to support the diffusion of information in special locations within a city, particularly in crowded spaces where current wireless technologies can exhibit congestion issues. Sparse connectivity, no infrastructure and limited resources further complicate the situation [1,2]. Routing methods for such sparse mobile networks use a different paradigm for message delivery. These schemes utilize node mobility by c Springer Nature Switzerland AG 2021  L. Barolli et al. (Eds.): IMIS 2020, AISC 1195, pp. 11–22, 2021. https://doi.org/10.1007/978-3-030-50399-4_2

having nodes carry messages, waiting for an opportunity to transfer messages to the destination or the next relay rather than transmitting them over a path [3]. Hence, the challenges for routing in OppNets are very different from the traditional wireless networks and their utility and potential for scalability makes them a huge success. Internet of Things (IoT) seamlessly connects the real world and cyberspace via physical objects embedded with various types of intelligent sensors. A large number of Internet-connected machines will generate and exchange an enormous amount of data that make daily life more convenient, help to make a tough decision and provide beneficial services. The IoT probably becomes one of the most popular networking concepts that has the potential to bring out many benefits [4,5]. The Fuzzy Logic (FL) is unique approach that is able to simultaneously handle numerical data and linguistic knowledge. The fuzzy logic works on the levels of possibilities of input to achieve the definite output. In this paper, we propose and implement two Fuzy-based systems: Node Elimination System (NES) and Node Selection System (NSS). We use three input parameters for NES: Node’s Distance to Event (NDE), Node’s Battery Level (NBL), Node’s Free Buffer Space (NFBS) and four input parameters for NSS: Node’s Number of Past Encounters (NNPE), Node’s Unique Encounters (NUE), Node Inter Contact Time (NICT) and Node Contact Duration (NCD). The output parameter Node Selection Possibility (NSP), for NES shows which IoT nodes have a very low possibility to be selected to take part in the selection process. While in NSS, NSP represents the possibility that IoT nodes will be selected to complete the task. We evaluate both systems and present the simulation results for different values of input parameters. The remainder of the paper is organized as follows. In the Sect. 2, we present the IoT node elimination and selection process. In Sect. 3, we introduce the design of fuzzy-based simulation systems. The simulation results are shown in Sect. 4. Finally, conclusions and future work are given in Sect. 5.

IoT Node Elimination and Selection Process

In order to make a more robust decision when selecting IoT nodes, a big pool of parameters must be selected and combined for multiple nodes. This redundancy of parameters, although covers a large space of possible combinations, decreases the performance by increasing overhead and computational time. The process of deciding how many parameters to use in a system for the selection process is limited by each node’s computational capabilities. To identify the proper parameters for each system, OppNets challenges were considered. In this work we have used two systems implemented in FL, NES and NSS. By using two systems, one for node elimination and one for selection, we eliminate redundant nodes from participating in the selection process, maximizing resource usage in the heterogeneous OppNet. Since most of the nodes are mobile devices with limited resources, battery level and storage will determine how long will the

IoT node operate. Furthermore, a long distance puts a strain to other resources such as battery, so we have selected it as one of the parameters for the first system. After each IoT node takes part in the elimination process, a second system is used to select the nodes which will benefit the task more. In an OppNet, nodes are continuously detected and evaluated for their usability and resource availability. However, to preserve these resources as much as possible we used NES as a system for eliminating nodes that do not fulfill the basic criteria for participating in task completion. Finding which nodes to remove from the selection process is an NP-Hard problem. That is why our proposed systems are based on FL. We will first evaluate the nodes based on the three most fundamental parameters battery, storage and distance to task. After we have assessed which nodes are less likely to be selected due to the lack of minimum resources, we eliminate them from participating in the selection process. Once the elimination process is completed, the second system NSS will evaluate nodes for their usefulness as potential candidates to execute diverse tasks. Parameters chosen for the second system differ depending on the type of system and the task at hand. If the node satisfies the criteria for completing a task, it is integrated into the OppNet as a helper. This node selection process is continued until enough nodes are found to complete the task.

Design of Fuzzy-Based Simulation Systems

In this work, we use FL to implement the proposed systems. Fuzzy sets and FL have been developed to manage vagueness and uncertainty in a reasoning process of an intelligent system such as a knowledge based system, an expert system or a logic control system [6–19]. Our proposed systems consist of one Fuzzy Logic Controller (FLC), which is the main part of our system and its basic elements which are shown in Fig. 1. Parameters represented from numerical inputs to linguistic variables as shown in Table 1, build the FRB. The control rules which are shown in Table 2 for NES and Table 3 for NSS have the form: IF “conditions” THEN “control action”. In Table 2 some rules are highlighted in red for the IoT nodes that do not fulfill the minimum requirements and are excluded from participating in the selection process, thus eliminated. When constructing FRB, a compromise between overfitting and computational power must be made.

Parameters Selection and Description

The proposed systems for node elimination and selection are shown in Fig. 2 and Fig. 3. The FMFs for each system are shown in Fig. 4 and Fig. 5 for NES and NSS, respectively. We have decided to use triangular and trapezoidal FMFs due to their simplicity and computational efficiency [20]. However, the overlap triangle-to-triangle and trapezoid-to-triangle fuzzy regions can not be addressed by any rule. It depends on the parameters and the specifics of their applications.

Simulation Results

In this work we proposed two systems, NES and NSS. We used NES to show which IoT nodes do not have the basic resources such as sufficient battery, sufficient storage and good distance from the task considering OppNets characteristics. The simulation results of NES are shown in Fig. 6. From these simulation results we eliminate IoT nodes that lack the necessary resources to participate in the selection system. In realistic OppNet environments, some IoT nodes might roam the network with random mobility patterns exploiting contacts to communicate. It is important to study the properties of contacts made between nodes, that is why for

M. Cuka et al.

Some encounters made between nodes are probabilistic which means that two nodes have met each other in the past or they follow a schedule which is known by both nodes. We have summarized this type of encounter as NNPE. If we compare Fig. 7(a) with Fig. 7(c) and Fig. 7(c) with Fig. 7(e), for NCD = 0.6 and NICT = 0.1, we see that NSP has increased 32% and 8%, respectively. NUE represents the number of new contacts that IoT nodes establish with other nodes. Comparing Fig. 7(e) with Fig. 7(f), for NICT = 0.9 and NCD = 0.5, NSD has increased 36%. Frequent new contacts mean more nodes are encountered and end-to-end delivery is maximized. IoT nodes that take a longer time to come in contact with other nodes will create less connections, thus the possibility that one IoT node gets selected, decreases with the increase of NICT. We can see the effect of NICT in NSP in Fig. 7(a), for NCD = 0.5. When NICT decreases from 0.9 to 0.5, NSP increases 20% and when NICT decreases from 0.9 to 0.1, NSP increases 40%. Contact durations between IoT nodes are very short due to high node mobility. However, contact duration must be long enough so that the message can be transferred during a single contact. For example, in Fig. 7(e), for NICT = 0.1 when NCD increases from 0.2 to 0.4, NSD increases 40%. For NCD from 0.4 to 0.6, it is evident that NSD remains unaltered because all these values of NCD are considered equally good amounts of contact duration.

Conclusions and Future Work

In this paper, we proposed two fuzzy-based systems for IoT node elimination and selection in OppNets. NES makes the decision which nodes should be excluded from the selection system while NSS makes the selection decision and chooses which IoT nodes from the remaining nodes are better suited for a certain task. In NES, we saw that IoT nodes that have sufficient basic resources are selected to go through the selection process for completing tasks. For NSS, NSP increases with the increase of NNPE and NUE and decreases with the increase of NICT. However, for NCD we need to find an optimal time for IoT nodes to stay in contact with each other. In the future work, we will also consider other parameters for IoT node selection and make extensive simulations and experiments to evaluate the proposed system.

Abstract. In this paper, we propose an intelligent Fuzzy-based Simulation System for Driver Risk Management in Vehicular Ad hoc Networks (VANETs). The proposed system considers Vehicle’s Environment Condition (VEC), Weather Condition (WC), Vehicle Speed (VS) and Driver’s Health Condition (DHC) to assess the risk level. The input parameters’ data can come from different sources, such as on board and on road sensors, sensors in the infrastructure and communications. Based on the system’s output i.e., risk level, a smart box informs the driver and provides assistance. We show through simulations the effect of the considered parameters on the determination of the risk level and demonstrate a few actions that can be performed accordingly.

Introduction

Traffic accidents, road congestion and environmental pollution are persistent problems faced by both developed and developing countries, which have made people live in difficult situations. Among these, the traffic incidents are the most serious ones because they result in huge loss of life and property. For decades, we have seen governments and car manufacturers struggle for safer roads and car accident prevention. The development in wireless communications has allowed companies, researchers and institutions to design communication systems that provide new solutions for these issues. Therefore, new types of networks, such as Vehicular Ad Hoc Networks (VANETs) have been created. VANET consists of a network of vehicles in which vehicles are capable of communicating among c Springer Nature Switzerland AG 2021  L. Barolli et al.

themselves in order to deliver valuable information such as safety warnings and traffic information. Nowadays, every car is likely to be equipped with various forms of smart sensors, wireless communication modules, storage and computational resources. The sensors will gather information about the road and environment conditions and share it with neighboring vehicles and adjacent roadside units (RSU) via vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) communication. However, the difficulty lies on how to understand the sensed data and how to make intelligent decisions based on the provided information. As a result, various intelligent computational technologies and systems such as fuzzy logic, machine learning, neural networks, adaptive computing and others, are being or already deployed by many car manufacturers [6]. They are focusing on these auxiliary technologies to launch and fully support the driverless vehicles. Fully autonomous vehicles still have a long way to go but driving support technologies are becoming widespread, even in everyday cars. The goal is to improve both driving safety and performance relying on the measurement and recognition of the outside environment and their reflection on driving operation.

Fig. 1. Proposed system architecture.

On the other hand, we are focused not only on the outside information but also on the in-car information and driver’s health information to detect a potential accident or a risky situation, and alert the driver about the danger, or take over the steering if it is necessary. We aim to realize a new intelligent driver support system which can provide an output in real-time by combining information from many sources. In this work we implement a fuzzy-based simulation system for driving risk management considering vehicle’s environment condition, weather condition, vehicle speed and driver’s health condition as input parameters. The model of our proposed system is given in Fig. 1. Based on the output

parameter value, it can be decided if an action is needed, and if so, which is the appropriate task to be performed in order to provide a better driving support. The structure of the paper is as follows. Section 2 presents a brief overview of VANETs. Section 3 describes the proposed fuzzy-based simulation system and its implementation. Section 4 discusses the simulation results. Finally, conclusions and future work are given in Sect. 5.

Vehicular Ad Hoc Networks (VANETs)

VANETs are a special case of Mobile Ad hoc Networks (MANETs) in which mobile nodes are vehicles. In VANETs nodes (vehicles) have high mobility and tend to follow organized routes instead of moving at random. Moreover, vehicles offer attractive features such as higher computational capability and localization through GPS. VANETs have huge potential to enable applications ranging from road safety, traffic optimization, infotainment, commercial to rural and disaster scenario connectivity. Among these, the road safety and traffic optimization are considered the most important ones as they have the goal to reduce the dramatically high number of accidents, guarantee road safety, make traffic management and create new forms of inter-vehicle communications in Intelligent Transportation Systems (ITS). The ITS manages the vehicle traffic, support drivers with safety and other information, and provide some services such as automated toll collection and driver assist systems [7]. Despite the attractive features, VANETs are characterized by very large and dynamic topologies, variable capacity wireless links, bandwidth and hard delay constrains, and by short contact durations which are caused by the high mobility, high speed and low density of vehicles. In addition, limited transmission ranges, physical obstacles and interferences, make these networks characterized by disruptive and intermittent connectivity. To make VANETs applications possible, it is necessary to design proper networking mechanisms that can overcome relevant problems that arise from vehicular environments.

Proposed Fuzzy-Based Simulation System

Although the developments in autonomous vehicle design indicate that this type of technology is not that far away from deployment, the current advances fall only into the Level 2 of the Society of Automotive Engineers (SAE) levels [16]. However, the automotive industry is very competitive and there might be many other new advances in the autonomous vehicle design that are not launched yet. Thus, it is only a matter of time before driverless cars are on the road. On the other side, there will be many people who will still be driving even on the era of autonomous cars. The high cost of driverless cars, lack of trust and not wanting to give up driving might be among the reasons why those people will continue to drive their cars. Hence, many researchers and automotive engineers

keep working on Advanced Driver Assistance Systems (ADASs) as a primary safety feature, required in order to achieve full marks in safety. ADASs are intelligent systems that reside inside the vehicle and help the driver in a variety of ways. These systems rely on a comprehensive sensing network and artificial intelligence techniques, and have made it possible to commence the era of connected cars. They can invoke action to maintain driver attention in both manual and autonomous driving. While the sensors are used to gather data regarding the inside/outside environment, vehicle’s technical status, driving performance and driver’s condition, the intelligent systems task is to make decisions based on these data. If the vehicle measurements are combined with those of the surrounding vehicles and infrastructure, a better environment perception can be achieved. In addition, with different intelligent systems located at these vehicles as well as at geographically distributed servers more efficient decisions can be attained. Our research work focuses on developing an intelligent non-complex driving support system which determines the driving risk level in real-time by considering different types of parameters. In the previous works, we have considered different parameters including in-car environment parameters such as the ambient temperature and noise, and driver’s vital signs, i.e. heart and respiratory rate for which we implemented a testbed and conducted experiments in a real scenario [2,4]. The considered parameters include environmental factors and driver’s health condition which can affect the driver capability and vehicle performance. In [3], we included vehicle speed in our intelligent system for its crucial impact on the determination of risk level. In this work, we consider the weather condition as a new parameter. The weather condition affects not just the driver visibility and its comfort but also the road condition, which is a critical aspect of many accidents. We use fuzzy logic to implement the proposed system as it can make real-time decisions based on the uncertainty and vagueness of the provided information [1,5,8–15,17,18]. The proposed system called Fuzzy-based System for Driving Risk Management (FSDRM) is shown in Fig. 2. For the implementation of FSDRM, we consider four input parameters: Vehicle’s Environment Condition (VEC), Weather

All the term sets for the linguistic parameters used for FSDRM are shown in Table 1. Based on the linguistic description of input and output parameters we make the Fuzzy Rule Base (FRB). The FRB forms a fuzzy set of dimensions | T (x1 ) | × | T (x2 ) | × · · · × | T (xn ) |, where | T (xi ) | is the number of terms on T (xi ) and n is the number of input parameters. FSDRM has four input parameters, with three parameters having three linguistic terms each and one parameter having four, therefore, there are 108 rules in the FRB, which is shown in Table 2. The control rules of FRB have the form: IF “conditions” THEN “control action”. The membership functions used for fuzzification are given in Fig. 3(a), Fig. 3(b), Fig. 3(c) and Fig. 3(d). In Fig. 3(e) are shown the membership functions used for the output parameter. We use triangular and trapezoidal membership functions because they are suitable for real-time operation.

Simulation Results

In this section, we present the simulation results for our proposed system. The simulation results are presented in Fig. 4, Fig. 5 and Fig. 6. We consider the VEC and WC as constant parameters. We show the relation between DRM and DHC for different VS values. The VS values considered for simulations are 0.1, 0.3 and 0.65, which simulate a slow, moderate and high speed, respectively. In Fig. 4, we consider the VEC value 0.2 and change the WC from 0.05 to 0.35. From Fig. 4(a), we can see that most of DRM values show extremely high driving risk. The only scenario when the DRM is decided as “High” is when the driver is driving very slowly and the health condition parameter indicates a very good status of his/her health. All other scenarios are decided as “Very High”, “Severe” or “Danger”, with the latter accounting for most scenarios. When the weather conditions are improved a little (see Fig. 4(b)), we see that the DRM values are decreased, with the lowest risk situation implying a driving scenario with a “Moderate” risk level. In Fig. 5, we present the simulation results for VEC 0.5. In Fig. 5(a) is considered the scenario with an uncomfortable vehicle and a very bad weather. By comparing with Fig. 4(b), we can see the improvements on the risk levels due to the increase of inside comfort for the same weather conditions. Since the inside

31

conditions are slightly better, the risk level is decreased and there is not such a high risk for an accident, especially when the driver is in good health condition and drives slowly. With the weather conditions getting better, there is not any scenario with the highest degree of risk and only a few situations are decided with a “Severe” driving risk. In Fig. 6, we show the results for a comfortable vehicle interior environment and for WC 0.05, 0.35, 0.65 and 0.95, representing “Extremely Bad”, “Very Bad”, “Bad” and “Good” weather conditions, respectively. A big difference on the DRM values is seen when the WC increases from 0.05 to 0.95. Weather conditions affect directly and indirectly the vehicle performance and the driver’s ability to drive; therefore, driving safely with a moderate speed is decided only when the weather condition is good. Driving with a high speed has a risk itself, regarding the weather conditions, thus, these situations are not decided with a ”Safe” driving risk level on any occasion. In the cases when the risk level is above the moderate level for a relatively long time, the system can perform a certain action. For example, when the DRM value is slightly above the moderate level the system may take an action in order to lift the driver’s mood, and when the DRM value is very high, the system could even decide to limit the vehicle’s operating speed to a speed that the risk level is decreased significantly.

Conclusions

In this paper, we proposed a fuzzy-based system to decide the driving risk management. We considered four parameters: vehicle’s environment condition, weather condition, vehicle speed and driver’s health condition. We showed through simulations the effect of the considered parameters on the determination of the risk level. In addition, we demonstrated a few actions that can be performed based on the output of our system. However, it may occur that the system provides an output which determines a low risk, when actually the chances for an accident to happen are high, or the opposite scenario, which is the case when the system’s output implies a false alarm. Therefore, we intend to implement the system in a testbed and estimate the system performance by looking into correct detection and false positives to determine its accuracy.

Abstract. With the rapid development of the Internet, Web applications have been used more and more widely in various industries, and the accompanying security issues have gradually received attention. In the field of network security research, in addition to defense technologies such as intrusion detection and firewall technology, forensic analysis and traceability of network attacks are also the focus of research. Based on this, this paper is devoted to mining the associations of attack traces existing in web application logs, and to provide assistance for forensic analysis and attack source tracing. In this paper we propose a method for analyzing associations of network attack traces based on Web logs. We collect features of common Web attack methods and extracts attack traces. We also propose attack event description models based on key attributes, and improves the Apriori algorithm to adapt the model. The attack trace correlation analysis method proposed in this paper makes full use of and analyzes the infrequently discovered correlations in the log data, which has greatly helped the development of network attack traceability technology.

1 Introduction At the current stage of the rapid development of Internet technology, more and more enterprises and institutions cannot run without Internet. Web applications, as an important part of the Internet, have penetrated into all walks of life, and some companies have used Web applications as a carrier of core business. In this context, the security of Web applications should be given enough attention. Under the current background of network security technology, there are already many types of attack methods for Web applications. OWASP will summarize the 10 most common security problems in Web application scenarios every year. Common web applications record logs, but the detail of logging is different by default. At present, web log-based research in network security research mostly focuses on the field of intrusion detection. For example, monitoring logs in real time to detect ongoing network attacks. Another part of log-based research involves the correlation analysis of network attack traces. But few studies have been conducted, and almost all of these methods have certain limitations and cannot fully utilize the effective information in log data. Based on the above background, in this paper we proposes a log analysis method. On the one hand, it can be combined with firewalls and intrusion detection systems to sense the ongoing network attacks. On the other hand, you can © Springer Nature Switzerland AG 2021 L.

analyze the attack behavior that has occurred, restore the attack path, find the characteristics of the attacker, and also restore the attack path in more detail in the case of certain missing log data. In this paper we proposes a method for analyzing multi-source web logs using association analysis technology. First, traces of attacks were extracted from a large number of multi-source logs according to the types of web attacks proposed by OWASP. The extracted traces of attacks include common types of web attacks such as sensitive file scanning, weak password brute force, and SQL injection. With reference to the characteristics of each vulnerability, the corresponding one or more log data was extracted as an attack trace. To facilitate the analysis of large amounts of data, it is necessary to model attack events. Combining traces from the same attack event, the content of the attack event includes key information such as the type of attack contained in the attack, the time of the attack, the source address, and the destination address. After the establishment of the attack event description model, we use the improved Apriori algorithm to perform correlation analysis on a large number of attack events. The original Apriori algorithm is also used for correlation analysis. However, we have improved it to adapt to the attack event description model. In order to verify the method proposed in this paper, a large amount of web log data was collected, and an attack trace extraction and correlation analysis experiment was designed. The experimental results show that the log correlation analysis method proposed in this paper is completely feasible and efficient, mining the correlation between attack traces that are easily ignored in Web logs. The structure of this paper is as follows. Section 2 introduces the related works of analysis algorithms and log data mining. Section 3 describes the construction of attack event model and the method of extracting attack traces. Section 4 introduces the attack trace correlation analysis method based on the improved Apriori algorithm. Section 5 designs experiments to verify the research method proposed in this paper. Section 6 describes the conclusions of the study and the advantages and disadvantages of the method.

3 Model Construction and Attack Trace Extraction 3.1

Model Construction

In order to facilitate subsequent trace extraction and data correlation analysis, an attack event description model needs to be constructed. The attack event description model proposed in this paper is used to combine network attack traces extracted from a large number of Web logs to restore the attack events recorded in the logs. A schematic diagram of this model is shown in Fig. 1.

Fig. 1. Attack event description model

In the model, the subject is a series of interconnected traces of web attacks. Each attack trace consists of four key attributes: timestamp, source address, destination address, and attack type name. Referring to the general characteristics of Web logs, each log message itself contains information related to these four key attributes. The default log style of commonly used web server software such as Apache/Nginx will record the time when each web request is generated. Take the time of the first web request in each web log file as a reference. Subtract the time generated by the first web request in this log file from the time of the web request corresponding to the extracted attack trace to obtain a relative time as the timestamp attribute of the attack trace, in seconds. For those attack types that require more than one log to analyze together, the

time corresponding to the first log message is used as the basis for generating timestamp attributes. The same Web log file is from the same server, so under normal circumstances all Web requests in the same file are sent to the same destination address, that is, the attribute IP.dst is the same. The IP.src attribute can also be obtained directly in each web log. The attribute of attack type name will be described in the introduction of trace extraction method. After extracting all attack traces in the web log, each attack trace is stored in json format data for subsequent analysis. The following definition is an example of an extracted attack trace: ð1Þ All attack traces are classified according to the two attributes IP.src and IP.dst. Traces where the both attributes are the same are considered the same attack event. The same attack event is sorted by time stamp, and the time stamp attribute is expressed by time in formula (1). The correlation between different attack traces in the same attack event is the content of this paper. After collecting a certain number of attack events, analyze the support between attack traces. At the same time, because the attack traces have a sequence, the forward correlation degree and the backward correlation degree between different attack traces are finally obtained. The expression of correlation degree has similarities with conditional probability, and the two major rules in association analysis——support and confidence are also related to probability. So in the attack event description model, the correlation between attack traces is expressed in the form of conditional probability. For example, P(B|A)represents the forward correlation degree from A to B, and P’(A|B) represents the backward correlation degree from B to A. The purpose of proposing two kinds of correlation degree is to consider the case where the log information is partially missing, and the traces of forward and backward loss can be recovered through known attack traces. In the analysis process, the analysis method with Apriori algorithm as the main body was used, and its algorithm content was improved to make it adapt to the model proposed in this paper. 3.2

Attack Trace Extraction

We uses feature-based data analysis methods to extract attack traces from log data. Because the technology studied in this paper does not have very high requirements for the extraction speed of attack traces, in the case of small data volumes, the specified feature extraction method is preferred, and the deep learning model is not considered. When the amount of subsequent data increases and the types of attacks that need to be extracted increase, then we will consider using a deep learning model. Figure 2 shows the framework of the attack trace extraction method.

Before extracting attack traces based on features, the log data needs to be cleaned first. There are some errors in the original log data. Without data cleaning, the accuracy of attack trace extraction will be affected. In the data set selected in this paper, the log format is fixed, so we can directly write a script to specify the format for data cleaning. Delete unnecessary data at the beginning and end of each log file, and delete useless data at the same time. Useless data includes: each log records a total of 27 entries with more than 10 blank entries, and data records have errors. Each log records a lot of information, including timestamp, number of requests, source address and port, destination address and port, Web request method, URL, User Agent, POST body, etc. The useful information is only the timestamp, source address, destination address mentioned in the previous section, and the URL, User Agent, and POST body used to extract the name of the attack type. Other information can be deleted directly. After data cleaning, a log file with only valid information is obtained. After obtaining the cleaned valid data, the data can be extracted.
