AN EFFICIENT TECHNIQUE FOR PREVENTING COOPERATIVE BLACKHOLE ATTACK IN MANET USING AODV PROTOCOL

Abstract

A mobile ad-hoc network (MANET) is a self-configuring infrastructureless network of mobile devices connected by wireless links. As there is no fixed infrastructure in MANET, mobile nodes need to communicate with each other by exchanging control and data packets to provide assured functionality to the network. For making communication possible in MANET, different routing protocols are used. Ad-hoc On demand Distance Vector (AODV) protocol is the principle routing protocol used in MANET. The AODV protocol is threaded by a security problem called cooperative black hole attack, in which all malicious nodes introduces themselves as having shortest path to the destination node. In this paper an approach has been proposed to prevent cooperative black hole attack using cooperative black hole prevention technique (CBPT). It works on the concept of using Three_Hop_Away_Information_Table (THAIT) and three routes from Source to three_hop_away node. The goal of this paper is to provide better security and better performance in terms of packet delivery using CBPT in the presence of black hole with affordable delay and overhead.
