Identifying, Avoidance and Performance Assessment of Black Hole Attack on AODV Protocol in MANET

Composition of mobile devices communicating with each other deprived of any infrastructure is a Mobile Adhoc Network (MANET). A mobile node in MANET has dynamic topology and they may move expeditiously that means stability is very less. The intruders take advantage of such individualities of MANET to carry out different varieties of attacks. Out of all these attacks, black hole attack is the most severe one. The routing protocol used by a malicious node is to proclaim itself as having the shortest route to the target node. Black hole node discards all the packets that finally go through it. In this paper, we simulated the Black Hole Attack on AODV protocol using NS-2.34 simulator and compare the parameters like Packet Delivery Fraction, Network Overhead and Average throughput and also proposed a solution to prevent and figure out this black hole attack on AODV protocol.
