Vehicular Ad hoc Networks (VANET) has emerged as a recognized advancement in wireless technologies. Each node in the network may be either a vehicle or Road Side Unit (RSU) which has to be equipped with the necessary communication facility. Every vehicle in VANET must be authenticated to establish a reliable and secure network communication. The AODV routing protocol which is normally applied in a VANET scenario does not detect malicious vehicles, if it exist. In this paper, a security mechanism has been incorporated in the AODV protocol to strengthen it as Robust AODV (RAODV) to detect a malicious vehicle. Sample architecture with centralized control unit, RSUs and some vehicles is illustrated to demonstrate the added security feature. AODV routing protocol has been applied in a simulated environment using NS-2 package. Performance metrics such as Packet Delivery Ratio, End to End delay, Routing Overhead and Number of dropped packets, for various vehicle speed were analyzed with the RAODV protocol.
