A Survey on Black hole Attack Detection Methods

MANET(Mobile Ad Hoc Networks) is important and growing technology, because of its characteristics such as mobility, easy deployment, also it doesn’t required any centralized management and predefined infrastructure, increases its applications in real life. But other side this characteristics becomes its disadvantage and it becomes vulnerable to several security threats. Black hole is the one of the most dangerous attack in MANET, in which adversary node claims that it has fresh and shortest path to the destination but in reality it doesn’t, and after receiving all packets from source it drops all packets. In this survey paper we study different black hole detection techniques.
