VANET: A Survey on Secure Routing

Vehicular Ad-Hoc Network is a sub branch of Mobile Ad-Hoc Network i. e. MANET. A VANET provides communication between vehicle to vehicles and vehicles to infrastructure. Now, road traffic activities are one of the most important daily routines. VANET provide us information that is required for better safety and driving. Security is major challenge in VANET. One of the major threats is Sybil attack, is a serious threat as they can affect the functionality of VANETs for the benefit of the attacker. The Sybil attack is the case where a single faulty entity, called a malicious node, can present or create multiple identities known as Sybil nodes or fake nodes. This paper detects and prevents the Sybil attack using new secure routing protocol. It is based on AODV protocol. Also it proven that multiple identities of fake node can create confusion in the VANET network or collapse entire network.
