Comparative Results

Vehicular Networks (VANETs) have received increased attention from researchers in recent years. VANETs facilitate various safety measures that help in controlling traffic and saving human lives. As VANETs consist of multiple entities, effective measures for VANET safety are to be addressed as per requirement. In this chapter, the authors review some existing schemes proposed for misbehavior detection. They categorize the schemes into two parts: data centric and non-data centric misbehaving detection. In data-centric misbehaving detection, the receiver believes the information rather than the source of the information. The authors compare schemes in each category with respect to their security strengths and weaknesses. The comparative results show that most of the schemes fail to address required security attributes that are essential for VANET safety.

Delay Tolerant

Opportunistic forwarding mechanism in Delay Tolerant Networks (DTN), are prone to get disconnected from the nodes in the network. These types of networks deal with intermittent connectivity, large delays.Existing routing protocols of DTNs fights with these issues, but fail to integrate the security available for delay tolerant networks,it is necessary to design a secure routing protocol to overcome these issues. There are centralized Trust Authority (TA) based security systems but the disconnection or failure of TA, affects the security model and network performance. It becomes crucial to have the distributed approach for security system and have multiple TAs working on security model. This reduces the possibility of poor network performance. The paper presents a distributed misbehavior detection system, and implements multiple TAs for implementing the security model for DTN.

Dynamic Context

Life-saving decisions in vehicular ad hoc networks (VANETs) depend on the availability of highly accurate, up-to-date, and reliable data exchanged by neighboring vehicles. However, spreading inaccurate, unreliable, and false data by intruders create traffic illusions that may cause loss of lives and assets. Although several solutions for misbehavior detection have been proposed to address these issues, those solutions lack adequate representation and the adaptability to vehicular context. The use of predefined static thresholds and lack of comprehensive context representation have rendered the existing solutions limited to specific scenarios and attack types, which impedes their generalizability. This paper addresses these limitations by proposing an ensemble-based hybrid context-aware misbehavior detection system (EHCA-MDS) model. EHCA-MDS has been developed in four phases, as follows. The static thresholds have been replaced by dynamic ones created on the fly by analyzing the spatial and temporal properties of the mobility information collected from neighboring vehicles. Kalman filter-based algorithms were used to collect the mobility information of neighboring vehicles. Three sets of features were then derived, each of which has a different perspective, namely data consistency, data plausibility, and vehicle behavior. These features were used to construct a dynamic context reference using the Hampel filter. The Hampel-based z-score was used to evaluate the vehicles based on their behavioral activities, data consistency, and plausibility. For comprehensive features representation, multifaceted, non-parametric-based statistical classifiers were constructed and updated online using a Hampel filter-based algorithm. For accurate representation, the output of the statistical classifiers, vehicles’ scores, context reference parameters, and the derived features were used as input to an ensemble learning-based algorithm. Such representation helps to identify the misbehaving vehicles more effectively. The proposed EHCA-MDS model was evaluated in the presence of different types of misbehaving vehicles under different context scenarios through extensive simulations, utilizing a real-world traffic dataset. The results show that the accuracy and robustness of the proposed EHCA-MDS under different vehicular dynamic context scenarios were higher than existing solutions, which confirms its feasibility and effectiveness to improve the performance of VANET critical applications.
