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. In this context, preventing or detecting malicious nodes launching gray hole or collaborative black hole attacks is a challenge. This paper 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 (CBDS) that integrates the advantages of both proactive and reactive defense architectures. Their CBDS method implements a reverse tracing technique to help in achieving the stated goal.
