Mobile Ad Hoc network is a self-composing network with a highly dynamic network topology. Although it has many advantages, there are still some safety problems in it. One of these problems is the black hole attack. The black hole attack is a typical attack to the Ad Hoc network and is also the main threat facing it. In this paper, the safety problems exist in the AODV protocol, which is a kind of routing protocol in the Ad Hoc, has been analyzed in detail. In the meanwhile, an improved Secure Ad Hoc On-Demand Distance Vector Routing called OSAODV has been proposed and realized based on the NS2. Finally, three set of experiments have been made, the results have shown that the OSADOV can avoid the black hole attack very well.
