A Mobile Ad hoc Network is an aggregation of mobile terminal that form a volatile network with wireless interfaces. Mobile Ad Hoc Network has no any central administration. MANET more vulnerable to attacks than wired network, as there is no central management and no clear defence mechanism. Black Hole Attack is one of the attacks against network integrity in MANET. In this type of attack all data packets are absorbed by Black Hole node. There are lots of techniques to eliminate the black hole attack on AODV protocol in MANET. In this paper a solution named Black Hole Detection System is used for the detection of Black Hole attack on AODV protocol in MANET. The Black Hole Detection System considered the first route reply is the response from malicious node and deleted, then the second one is chosen using the route reply saving mechanism as it come from the destination node. We use NS-2.35 for the simulation and compare the result of AODV and BDS n solution under Black Hole attack. The BDS solution against Black hole node has high packet delivery ratio as compared to the AODV protocol under Black hole attack and it’s about 46.7%.The solution minimize the data loss and decrease the average Jitter 5% and increase the throughput.
