Sybil attack can counterfeit the traffic scenario by sending false messages with multiple identities, which often causes a traffc jam and even leads to vehicular accidents in vehicular ad-hoc network (VANET). It is very difficult to be defended and detected, especially when it is launched by some conspired attackers using their legitimate identitiess. Since few years, Vehicular Ad hoc Networks deserve much attention. VANET technology uses moving cars as nodes in network to create a mobile network it turns every participating car into a wireless router or nodes, allowing cars approximately hundred to three hundred meters of each other to connect and in turn, create a network with a wide range. The development of wireless communication in VANET implies to take into account the need of security. In VANET, many attacks depends on possibility of the attacker generate multiple identities to simulate multiple nodes. Moreover, due to the limited communication range of a vehicle, the cooperation between nodes is essential. This necessity of cooperation shows the vulnerability of the need of fake nodes detection. In this paper we are checking Sybil attacks in VANET.
