Mitigating Multiple Cooperative Black Hole Attack Using DRI in Wireless Ad Hoc Networks
Mobile Ad hoc NETworks (MANETs) are extensively used in military and civilian applications. The dynamic topology of MANETs allows nodes to join and leave the network at any point of time. This generic characteristic of MANET has rendered it vulnerable to security attacks. In this paper, the authors address the problem of coordinated attack by multiple black holes acting in-group. They present a technique to identify multiple black holes cooperating with each other and a solution to discover a safe route avoiding cooperative multiple black hole attack.
