A generic request/reply based algorith for detection of blackhole attack in manet: Simulation result

Mobile Ad Hoc Network (MANET) technology is emerging technology in recent year. Many researchers find future of networking in it. MANET is simple and effective wireless technology which depends on mutual trust for communication. Due to limited processing and energy power, developers used the lightweight protocol to build it. This made developers concentrate on basic functionality (like routing, route discovery) and less on security aspects. One of its examples is mutual trust between nodes. In MANET, nodes are interdependent for communication as well as data transmission which need mutual trust between nodes. This mutual trust flaw is exploited by attackers to perform a different kind of attacks by injecting malicious node in the network. One of these attacks is blackhole attack. In this study, the behavior of blackhole attack is discussed and have proposed a lightweight solution for blackhole attack which uses existing functions. Simulation results of proposed system are discussed at the end of the paper.
