Uncovering & anticipation of malicious attacks in networking field is an important and challenging security issue in Vehicular Ad-hoc NETworks (VANET).VANETs are dynamic wireless networks without any infrastructure. The dynamic topology of VANET allows nodes to join and leave the network at any point of time. Wireless VANET is particularly vulnerable due to its fundamental characteristics such as open medium, dynamic topology, distributed cooperation and constrained capability. So security in VANET is a complex issue. These networks are weak against many types of attacks.
