Abstract:

A new scheme for preventing the "black hole attack" is proposed. It tests the destination node and verifies the node in the reverse direction using control messages and data messages. Nodes check and locate the black hole and remove it from the net. The intermediate nodes also verify the dubious node to minimize the damage caused by the black hole attack. Our scheme can effectively prevent the "black hole attack" and has low network overhead and transmission delay compared to the existing schemes.

Key words: Ad Hoc network, secure route, AODV protocol, black hole attack
