The paper proposes an optimized and energy-efficient Ad Hoc On-Demand Distance Vector (AODV) routing protocol for Mobile Ad Hoc Network (MANET) based on dynamic forwarding probability, in which the Route Request (RREQ) packets are randomly controlled to increase the network lifetime and reduce packet loss in the flooding algorithm. The results are assessed using various network performance factors after implementing and integrating them into Network Simulator (NS2). According to the simulation findings, the proposed technique effectively reduced RREQ propagation messages. It is more efficient, has a longer network lifetime, and uniformly utilizes nodal residual energy, enhancing network throughput and minimizing routing overhead when compared to regular and modified AODV protocols.
