On the Sybil attack detection in VANET

Since few years, Vehicular Ad hoc Networks deserve much attention. The development of wireless communication in VANET implies to take into account the need of security. In VANET, many attacks rely on having the attacker generate multiple identities to simulate multiple nodes: this is called the Sybil attack. In this paper, we propose a precise quantification of the effects of various assumptions (type of antenna, transmission signal strength) on the effectiveness of a Sybil attack.
