A survey on Wormhole attack on VANET

VANET

Security of nodes is one of the major effects that exist in Vehicular Ad-hoc network. Vehicular Ad-hoc networks are increasingly used to avoid accidents, traffic control and management of toll stations and public areas. In this paper we will study about wormhole attack. Wormhole attack is the one of the dangerous attack in network layer. In wormhole attack two or more malicious nodes can create a tunnel and transmit the data from one malicious node to another malicious node through tunnel. This paper describes all routing attacks and briefly describes wormhole attack. In this paper also describes wormhole detection and prevention techniques by literature survey
