Authors- Dr. J. Viji Gripsy, V. Selva Swathi

Abstract-In Mobile Ad-Hoc Networks (MANETs), secure and efficient route discovery is essential due to the vulnerability of these networks to various security threats, such as black hole, Sybil, and wormhole attacks. This paper proposes a trust-based secure route discovery mechanism designed to enhance the reliability and security of communication in MANETs. By evaluating node behavior and assigning trust values based on packet forwarding success, cooperation, and reliability, the proposed mechanism identifies and isolates malicious nodes. The performance of the proposed method is evaluated and compared with traditional routing protocols such as AODV, DSR, and SAODV. Simulation results demonstrate that the proposed method significantly improves key metrics such as Packet Delivery Ratio (PDR), Routing Overhead, Throughput, and Energy Consumption, thereby ensuring more secure, efficient, and scalable communication. This work highlights the potential of trust-based mechanisms in enhancing the robustness and security of MANETs, with applications in dynamic and large-scale environments.
