Abstract: Black hole is a malicious node that always gives the false replay for any route request without having specified route to the destination and drops all the received packets. This can be easily employed by exploiting vulnerability of on demand routing protocol AODV. Within mobile Ad hoc networks black hole attack is a harsh threat which is able to prevent by broadcasting the malicious node id to the entire nodes in the network. The obtainable method recognized the attacked node, retransmit the packets and once more find a new way as of source to destination. Here the proposed method to prevent black hole attack with reduced energy consumption of the network this results in improving lifetime by minimizing the packet loss and improved throughput of the network.
Keywords: Ad-hoc, AODV, Black Hole.
