ISOLATION OF BLACKHOLE ATTACK IN MANET USING MAODV PROTOCOL WITH CA ALGORITHM

Abstract

Mobile Ad-hoc Network (MANET) is a self-organized system encompassed of mobile nodes without any infrastructure. Security is a decisive requisite in Mobile Ad-hoc Network (MANETs) when accessed to wired networks. Blackhole attack is a arduous issue to be addressed in MANET. Blackhole node falsely claims that it has the shortest path to the destination and dumps the packet that is supposed to be forwarded. In order to reduce the effects of Blackhole attack, we are modifying the AODV protocol and proposing counter attack algorithm that provides a efficient way to mitigate such attacks.
