Geographical Routing Protocols in VANets: Performance and Security Analysis

Abstract

Vehicular ad hoc networks (VANETs) enable communication between automobiles and communication equipment positioned along the street to provide road safety and convenience applications. Security is a must for all of these applications. Due to its highly dynamic architecture and frequent connectivity breakdowns, security is a significant challenge in automobile ad-hoc networks. Due to the open nature of wireless communication, the attacker can overhear and change the messages broadcast by another node. We explored security vulnerabilities against VANETs spatial routing protocols in this article. Then, we suggested a novel security solution based on an Intrusion Detection System Algorithm that would provide adequate protection against black holes and jellyfish attacks.

A Modified On-Demand Vector Distance Routing Protocol Incorporating Alternate Vehicle-RSU-Vehicle and Vehicle-RSU- RSU Paths

“…The improvement in the throughput is due to the flexibility added by the alternative paths utilized by the proposed method. Besides, the proposed method does not overload the network in the route discovery process as implemented by Mubarek, Aliesawi [18], Zhang, Xiao [28], Al-Shabi [4], Ahamed and Vakilzadian [2], and Ebadinezhad [11].…”

“…Yet, such an approach increases the overhead significantly. Ahamed and Vakilzadian [2] extended the work of Abedi, Fathy [1] by selecting the next-hop using the speed, direction, and position of vehicles. Ebadinezhad [11] proposed to hop clustering to simplify routing and ensure a better quality of service.…”

“…Moussaoui, Djahel [17] Using the location of the destination in the route discovery stage Reduce overhead Mubarek, Aliesawi [18] Using location and distance in the route discovery stage Reduce overhead Zhang, Xiao [28] Using historical trajectory in the route discovery stage Reduce overhead Al-Shabi [4] Using message multi-casting in the message transmission stage Reduce discarding Ahamed and Vakilzadian [2] Using direction, speed, and distance in the route discovery stage Reduce overhead Ebadinezhad [11] Using hop clustering to simplify routing…”

Blockchain Driven Metaheuristic Route Planning in Secure Vehicular Adhoc Networks

“…Various researcher scholars made enormous efforts in their work which widely covered several forms of attacks. Several outlines were created and enhanced till now for offering security solutions to assaults in VANETs [4,5].…”
