Defending Against Collaborative Attacks by Malicious Nodes in MANETs: A Cooperative Bait Detection Approach

Abstract— Defending Against Collaborative Attacks by Malicious Nodes in MANETs: A Cooperative Bait Detection Approach. In mobile ad hoc networks (MANETs), a primary requirement for the establishment of communication among nodes is that nodes should cooperate with each other. In the presence of malevolent nodes, this requirement may lead to serious security concerns; for instance, such nodes may disrupt the routing process. Preventing or detecting malicious nodes launching grayhole or collaborative blackhole attacks is a challenge. Attempts to resolve this issue by designing a dynamic source routing (DSR)-based routing mechanism, which is referred to as the cooperative bait detection scheme < Final Year Projects 2016 > CBDS, that integrates the advantages of both proactive and reactive defense architectures. Our CBDS method implements a reverse tracing technique to help in achieving the stated goal.
