Detection and Mitigation of DoS Attacks in VANET Using Secured Minimum Delay Routing Protocol

In vehicular Ad Hoc network security is one of the features that need to be investigated seriously. In vehicular ad hoc network the vehicles move and communicate with each other and with the roadside unit (RSU) as well. The nodes are self-organized, highly portable and free to share so any node can interact with any other node resulting in security breach if there is any attack in the network. There are various attacks where the vehicles and RSUs are prone to attackers. Among those security attacks the denial of service attack and the distributed denial of service attack is given prominence and discussed in this paper. We have proposed Secured Detection of Dos Packet Algorithm for Denial of Service attack incorporated in the proposed Secured Minimum Delay Routing Protocol. We have evaluated the performance in NS3 using various parameters such as throughput and minimum delay with Adhoc on Demand Distance Vector AODV protocol and showed that the proposed algorithms are cost effective to mitigate the attacks.
