Abstract

the responsibility of every vehicle is to forward the traffic status to requester vehicles. As same as MANET due to open medium security is always the major concern in VANET. The attacker vehicle drops a huge amount of data packets that contain the information of traffic status. In this paper, we proposed the secure VANET communication in the presence of RSU. RSU identified the attacker vehicles by that unusual interference in communication. The RSU collects the information from vehicles and forwarded it to other vehicles or other RSU. The proposed Attack Prevention algorithm is applied to RSU to recognize the attacker vehicle activities. The RSU after identified it block their functionality of communication. We assume that RSUs are deployed along the highway which is at least several kilometers far from each other. On the highway, maybe some vehicles travel faster or slower than average, but we assume the majority of vehicles travel in normal or similar velocities. The aim of this research is to providing security against malicious attacks, to allow new proposed models to build their work on solid realistic models against packet dropping attack. The performance of the proposed secure algorithm is compared with the old Base-line scheme and ART scheme in VANET. In this proposed scheme, vehicles obtain traffic data when they pass by a roadside unit (RSU) and then share the data after They travel out of the RSU's coverage. The performance of the proposed scheme is better than an existing scheme in terms of providing security and overcome from the problem of congestion to manage traffic in a network.
