Abstract

Vehicular Ad hoc networks (VANETs) are considered as a promising approach for facilitating road safety, traffic management and infotainment dissemination for drivers and passengers. The development of wireless communication in VANET implies to take into account the need of security. Many attacks rely on having the attackers generate multiple identities to simulate multiple nodes, this is called Sybil attack. In this paper, we discuss various approaches proposed by different researchers to defend against Sybil attack.
