In mobile ad hoc networks (MANETs), an essential requirement for the foundation of communication among
nodes is that nodes should coordinate with one another. In the presence of malicious nodes, this requirement may lead
serious security concerns for instance, such node may disturb the routing process. In this context, preventing or detecting
malicious nodes launching grayhole or collaborative black hole in challenge. This project attempts to determine this
issue by designing a dynamic source routing (DSR) based routing mechanism, which is referred to as the cooperative
bait detection scheme(CBDS), that coordinates the advantages of both proactive and reactive defense architectures. Our
CBDS system implements a reverse tracing technique to help in achieving the stated goal. Ruse results are provided,
displaying, demonstrating , exhibiting that in the occurrence of malicious-node attacks, the CBDS outperforms the DSR,
2ACK, and best-effort fault-tolerant routing (BFTR) protocols (chosen as benchmarks) in conditions of packet delivery
percentage , proportion , rate and routing overhead (chosen as performance metrics).
