Using clustering scheme: Prevent reply attack in vehicular ad-hoc networks (VANET)

Abstract Many researchers work on VANET which is a hot topic for today’s research work. VANET transfers data, messages sent and makes life safe but lots of consequences also occur. Among them, there are lots of attacks that can happen in VANET. Replay attacks, DoS attacks, and DDoS attacks are among them. Many researchers work to detect replay and DDoS attacks but they do not provide any solution for preventing the attacks. Some researchers provide some researches with algorithms to prevent replay attacks. All of them apply V2I communication without clustering to prevent replay attacks but they cannot prevent it with 100% accuracy. They do not apply any clustering formula to prevent replay attacks. To prevent replay attacks I will apply V2V communication with clustering formula. By using SUMO, NS3 I will prove that applying the clustering formula prevents attacks more than without applying it to the cluster.
