Detection of Black Hole Attack and Performance Analysis of AODV Protocol in MANET (Mobile Ad Hoc Network)
Abstract: 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 central administration. MANET is more vulnerable to attacks than wired network, as there is no central management and no clear defense 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 lot 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 considers the first route reply as the response from malicious node and deletes it, then the second one is chosen using the route reply saving mechanism as it comes from the destination node. We use NS-2.35 for the simulation and compare the result of AODV and BDS 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 data loss, reduces the average Jitter by 5% and increases the Throughput.
