Detection and Prevention of Black Hole Attack in MANET
Journal Title: International Journal of Scientific Research and Management - Year 2016, Vol 4, Issue 9
Abstract
The traditional AODV protocol is vulnerable to the well - known black hole attack. In case of multipath AODV, when one path is affected by blackhole attack, then source node can choose another alternative path. In this paper we propose a new type blackhole a ttack mainly targeting multipath AODV. To the best of our knowledge there is no blackhole attack which specifically targets multipath AODV. Broadly speaking, in the proposed blackhole attack, the attacker looks for nodes through which many alternative path s of multipath AODV passes through. Such nodes are selected and blackhole attack is launched targeting them, thereby damaging more number of paths in a single attempt.Further, the attacker selects only those genuine nodes through more than a threshold numb er of alternative paths pass through, thereby facilitating the attacker to use less number of nodes. So the attack scheme is power aware. Finally we also propose an IDS to detect the proposed energy aware blackhole attack. NS2 experimental results show the validity of the proposed attack.
