Incentive-Driven Approach for Misbehavior Avoidance in Vehicular Networks

Abstract

For efficient and robust information exchange in the vehicular adhoc network, a secure and trusted incentive reward is needed to avoid and reduce the intensity of misbehaving nodes and congestion especially in the case where the periodic beacons exploit the channel. In addition, we cannot be sure that all vehicular nodes eagerly share their communication assets to the system for message dissemination without any rewards. Unfortunately, there may be some misbehaving nodes and due to their selfish and greedy approach, these nodes may not help others on the network. To deal with this challenge, trust-based misbehavior avoidance schemes are generally reflected as the capable resolution. In this paper, we employed a fair incentive mechanism for cooperation aware vehicular communication systems. In order to deploy a comprehensive credit based rewarding scheme, the proposed rewardbased scheme fully depends on secure and reliable cryptographic procedures. In order to achieve the security goals, we used the cryptographic scheme to generate a certified public key for the authenticity of every message exchange over the network. We evaluated the friction of misbehaving vehicles and the effect of rewarding schemes in context with honest messages dissemination over the network.

Adapted Speed System in a Road Bend Situation in VANET Environment

“…They have found use in decentralized defense systems. Some other applications [16][17][18][19] are in transportation, logistics, computer graphics and geographic information systems. They are widely supported in networked and wireless environments to provide automated and dynamically shared workloads, higher scale, and resilient networks with self-healing capabilities.…”

A Novel Fuzzy Logic-Based Scheme for Malicious Node Eviction in a Vehicular Ad Hoc Network

“…Some nodes attempt to postpone relaying packets. Our scheme excludes these nodes by punishing them according to the cost function in equation (8). Nodes that act bad are excluded from VANET by our scheme.…”

“…These characteristics include security, unpredictable growth and decrease of nodes, random topology, high node mobility, and fluctuating interference. Unfortunately, the dynamic nature and flexibility of accessing VANET's spectrum have attracted malicious nodes' attention, making VANET a target of malicious operations [8]. As a result, typical wireless network security schemes cannot be directly applied in VANET since they result in poor network performance regarding data accuracy, delay, packet delivery ratio, and throughput.…”
