Security Aware Adhoc on Demand Distance Vector Routing Protocol in Vehicular Adhoc Network

Abstract

Uncovering & Anticipation of malicious attacks in networking field is an important and challenging security issue in Vehicular Adhoc Networks (VANET).VANETs are dynamic wireless networks without any infrastructure. The dynamic topology of VANET allows nodes to join and leave the network at any point of time. Wireless VANET is particularly vulnerable due to its fundamental characteristics such as open medium, dynamic topology, distributed cooperation and constrained capability. So security in VANET is a complex issue. These networks are weak against many types of attacks. Black hole attack which is one of the possible attacks on AODV routing protocol in vehicular ad hoc networks. In this attack, a malicious node advertises itself as having freshest or shortest path to specific node to absorb packets to itself. The effect of Black hole attack on Adhoc network using AODV as a routing protocol will be studied in this paper. The proposed solution that is capable of detecting and removing Black hole nodes in the VANET at the initial stage itself without any delay. Furthermore, we investigate solution for increasing security in these networks.
