ABSTRACT
Vehicular Ad hoc Network (VANET) needs security to implement the wireless environment and serves users with safety and comfort applications. Attackers generate different attacks in vehicular network. In this paper, first phase implementation of attacker node in AODV routing protocol in VANET and in second phase identify malicious node with watchdog intrusion detection system. Once the attacker node is identified we will prevent it tocommunicate with other neighbor nodes in network with the help of Beyesian network theory. From Beyesiannetwork theory find probability of the neighbouring node being attacker node. To make secure AODV connection with generate new Route Request Packet (RREQ) in VANET.
