A Survey on Techniques of Identifying Black Hole in MANET

Renuka sharma, Sandeep Tayal

Abstract


MANET stands for mobile ad-hoc network where group of mobile nodes can move freely and communicate with each other. These nodes are not bound to fixed infrastructure. Hence are vulnerable to attacks and one such common attack is black hole attack. Black hole attack is an attack where one malicious node tries to disguise itself in having address and shortest path to any destination. And as the source transmits its data to this node it grabs all the data and do not send it further to the destination and as a result disrupt the communication. In this paper we have surveyed many mitigation methods to detect and prevent black hole attack and all used AODV protocol.
