A secure anonymous on-demand routing protocol to defend wormhole attack in Vehicular Adhoc Network

Vehicular Ad-Hoc Network is a sub class of MANETs (Mobile Ad-Hoc Networks). It`s a technology that provide secure driving environment by wireless communication between the vehicles. The technique of self-driving vehicle is more significant in today`s world. VANET converts each participating vehicle into wireless sensor nodes that allow vehicles to communicate among themselves. It creates a network of wide range. Due to non-centralized infrastructure, self-driving and Ad-Hoc nature of VANETs it`s vulnerable to various critical attacks that breach the security. One of the critical attacks is wormhole attack which mainly occur least two or more malicious nodes. It enables an attacker to capture packets at one location and tunnels them to another location forming a wormhole link in-between the legitimate nodes of the network. In this paper, secure routing protocol ANODR is implemented to prevent the wormhole attack in VANETs. The ANODR prevents strong adversaries from tracing a data packet flow back to its originator and for location privacy problem; ANODR ensures that adversaries/attackers cannot discover the real identities of authenticated transmitters. The performance of ANODR is evaluated on the basis of metrics like throughput, end-to-end delay, total packet received and jitters.
