In Mobile Ad hoc Networks (MANETs), the nodes form a local network by communicating and collaborating with each other since each node acts as a router by receiving and transmitting data. Serious security problems can arise if nodes become malicious and disrupt the network operations.

The current project presents a new methodology to identify and eliminate the malicious nodes utilizing the Dynamic Source Routing (DSR) operation, which incorporates the advantages of proactive and reactive techniques. A dubious node is employed to prompt the malicious nodes to self-advertise, and then a reverse tracking method is used to identify and eliminate the malicious nodes. The malicious nodes are identified through an energy-oriented tracking mechanism that monitors the energy levels of all the nodes in the network. Simulation results show that the proposed methodology protects the integrity and uninterrupted operation of the network.
