Detection of Wormhole Attack in VANET

As security is one of the important issues in Vehicular Adhoc Networks (VANETs), it is required to deal with the threats related to them and one such severe threat is the wormhole attack in which the hacker node grabs the network traffic from one point and directs to another location that may drop the packets. In this paper, a scheme has been proposed which includes the RTT (Round Trip Time), usage level of links and count of neighbors to find the wormhole nodes in VANET. The proposed scheme is assessed and simulated against AODV protocol on NS-2 simulator. The efficiency of the nominated scheme is validated through simulation results.
