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.
