Abstract

A vehicular ad hoc network or VANET is a self-organised group of vehicles connected by wireless links in an infrastructure-free network. This type of network is standalone and cheaper than other networks. In VANET, security is a primary issue to ensure secure data delivery between sender and receiver in a hostile environment. There are some challenges still related to VANET that need to be surmounted in the field of security. This paper presents a security scheme to communicate securely during a Sybil attack on VANET. The Sybil attacker is very harmful, and their reorganisation is also difficult if the network connection is not static and node movement is not fixed. The property of this attack is to present two different identities in the network. The proposed Sybil Attacker Prevention using Network Behaviour (SAPNB) security scheme will detect the attack identification and block their whole misbehaviour activity. The Sybil attacker is identified through their multiple identities and by the number of nodes performing the same activities as the attacker in a dynamic network. The attacker’s misbehaviour is enhanced according to time, and after some time, the performance of the whole network is dumped in a dynamic network. The attacker has been considered in simulation, and in both scenarios, the Sybil attacker is active in misbehaviour. The proposed security scheme provides better results and completely turns off attacker nodes in VANET. The proposed SAPNB security scheme provides better results and completely turns off attacker nodes in VANET.
