Abstract:

A Mobile Ad-Hoc Network (MANET) is an autonomous network that consists of mobile nodes that communicate with each other over wireless links. In the absence of a fixed infrastructure, nodes have to cooperate in order to provide the necessary network functionality. MANET is particularly vulnerable to security threats due to its fundamental characteristics such as open medium, dynamic topology, distributed cooperation and constrained capability. Due to the inherent characteristics, MANET is unprotected to various types of security attacks. Black hole is one of these attacks in which a malicious node announces the fresh and shortest path to a destination node and then drops/discards all data packets that subsequently go through it. Many researchers have proposed different techniques for preventing and detecting this attack. In this paper, we have presented a technique which can mitigate blackhole attack in Adhoc networks with minimal increase in end-to-end delay and routing overhead
