Implementation of a Novel Technique for a Secure Route by Detection of Multiple Blackhole Nodes in Manet
Pages : 56-59
Mobile Ad hoc Networks is a self-configuring, infrastructure less network which consists of independent mobile devices that can communicate via wireless medium. Each mobile device can move freely and changes their links to other devices frequently. Security is an essential part of ad hoc networks. Without any centralized infrastructure, dynamic topology, limited security and resource constraints, it is vulnerable to various attacks and black hole attack is one of them. In black hole attack, the malicious node advertises itself as having the shortest path to the destination and falsely replies to the route requests, and drops all receiving packets. In this paper, a mechanism to detect the black hole nodes has been implemented.
Keywords: MANET, Black hole.
