MANET (Mobile Ad-hoc network) is type of network which is comprised of moveableness vertices which are connected to form a wireless network. The connected vertices can move very freely as there is no fixed infrastructure for the network. Black hole attack is a DOS attack where one of the vertices in the network is mischievous which tries to capture all the datagrams passing through it by sending a false reply to the origin vertex. In this paper an improvement is made to the existing AODV protocol to mitigate the black hole attack in Manets. The proposed method finds the mischievous vertex and avoids the delivery route through the mischievous vertex. The simulations were experimented in ns2 and the observations prove that the implemented approach works well for various performance metrices like Packet delivery ratio, End to End delay and throughput.
