Executive Summary

Mobile ad-hoc networks are prone to various security vulnerabilities because of its characteristics mainly high mobility of nodes, and no well defined architecture. Security measures are difficult to implement as there is no central administration. Several attacks on Mobile ad-hoc network have been identified so far and Black hole attack is one of them. In this paper, the authors discuss black hole attack on Ad-hoc network and propose a solution to the hijacked node behaving as black hole node. A scenario has been considered where a node inside network has been intruded and compromised to cause black hole attack. The proposed security solution modifies original AODV using a hierarchical based intrusion detection method to identify hijacked node and exclude the particular node from network.
