Performance Analysis of Black Hole Attack on different MANET Routing Protocols

A Mobile Ad-hoc NETwork (MANET) is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Due to the openness of its nature it is vulnerable to various kinds of threats and malicious nodes are difficult to detect since every node participates in the operation of the network equally. One of the security thread is Black hole attack in which the traffic is redirected to such a node that actually does not exist in the network. It’s an analogy to the black hole in the universe in which things disappear. The scope of this paper is a study and analysis the performance of MANET Routing Protocols like DSDV, DSR, AODV, OLSR and ZRP with or without malicious attack like black hole attack and the parameter used to judge the performance analysis are packet delivery ratio, average throughput, average end to end delay and Packet Drop Rate using NS2 under different scenarios. Keywords— MANET, OLSR, AODV, ZRP, Black hole attack.
