Abstract: Ad hoc is wireless, in dependable infrastructure dynamic and self organize network create among different mobile host. Network generally exists in a Disaster recoveries, military activities emergency operation .Routing protocol have a major role in mobile network, which are affected from different attacks. Ad hoc on demand distance vector (AODV) routing protocol is suitable for routing protocol. Black hole attack is a serious hazard, in this attack a malicious node add spoof route and advertise shortest path to destination node and absorbs all data packet in it. In this paper, we have surveyed and compare the existing solution to black hole attack on AODV protocol and their demerit.

Keywords: AODV, Black hole attack, Residual energy, Routing overhead.
