Analysis And Detection Of Black Hole Attack In MANET

Swati Saini, Vinod Saroha

Abstract: An Ad hoc network is the network with no fixed infrastructure. There is no central administrator so any node can come and move in and outside of the network in a dynamic manner. This makes it more dynamic and complex which makes it more prone to attacks. They can attack either active or passive. Some effects of malicious nodes are Denial of service, Routing table overflow, Impersonation, Energy consumption, Information disclosure etc. A black hole attack node attracts all packets by falsely claiming a fresh route to the destination node and absorbs them without forwarding them to destination. In this paper a mechanism based on FUZZY LOGIC is proposed to detect the black hole attack in MANET with AODV protocol. An introduction of black hole in MANET with NS2 (2.35) is done, after applying the detection technique result reflects the performance. This paper is intended for audience having prior knowledge about network routing protocols and its related quantitative performance metrics.
