Mobile Ad Hoc Networks (MANETs) consist of wireless mobile nodes which coordinate with each other to form temporary network without its pre-existing infrastructure. AODV is popular Ad-hoc distance vector routing reactive protocol which is used to find correct & shortest route to destination. Due to openness, dynamic, infrastructure-less nature, MANET are vulnerable to various attacks. One of these possible attacks is a Black Hole Attack in which a mobile node falsely replies to the source node that it is having a shortest path to the destination without checking its routing table. Therefore source node send all of its data to the black hole node and it deprives all the traffic of the source node. In this paper, We are proposing a technique to detect and prevent the multiple black hole nodes from MANET so that source to destination communication can be made easily. We also analysed the performance of the network in terms of number of packets sent, received, throughput, energy of network before attack and after detection & prevention of Attack. From these analysis, we can conclude that performance decreased due to attack can be improved after detection & prevention black hole attack in MANET.
