Vehicular ad hoc networks (VANETs) are becoming popular and promising technologies in the
modern intelligent transportation world. They are used to provide an efficient Traffic
Information System (TIS), Intelligent Transportation System (ITS), and Life Safety.
The mobility of the nodes and the volatile nature of the connections in the network have made
VANET vulnerable to many security threats. Black hole attack is one of the security threat in
which node presents itself in such a way to the other nodes that it has the shortest and the
freshest path to the destination.
Hence in this research paper an efficient approach for the detection and removal of the Black
hole attack in the Vehicular Ad Hoc Networks (VANET) is described. The proposed solution is
implemented on AODV (Ad hoc On demand Distance Vector) Routing protocol one of the most
popular routing protocol for VANET. The strategy can detect both the single Black hole attack
and the Cooperative Black hole attack in the early phase of route discovery.
The simulation is carried on NS2 and the results of the proposed scheme are compared to [14]
and the fundamental AODV routing protocol, this results are examined on various network
performance metrics such as packet delivery ratio, throughput and end-to-end delay. The found
results show the efficacy of the proposed method as throughput and the delivery ratio of the
network does not deteriorate in presence of the back holes.
