Detection and Prevention Of Cooperative Black Hole Attack in a MANET
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 5
Abstract
A mobile ad hoc network (MANET) is a selfconfiguring infrastructure-less network of mobile devices connected wirelessly. In MANETs, security plays a major role as the mobile nodes can join and leave the network randomly due to the continuous movement of the mobile nodes. In this paper, a novel method for detection and prevention of cooperative black hole attack in MANETs, by thresholding RREP sequence number, is proposed. It is implemented using AODV routing protocol in the NS2 simulations. The experimental results are obtained by varying the concentration of black hole nodes and are analyzed in terms of throughput, end to end delay and packet delivery ratio. The results demonstrate the effectiveness of the proposed method.
