MANETs are a type of wireless ad hoc network characterized by a wireless medium. The MANET's inherent characteristics, like dynamic change in topology and lack of central administration, reduce the possibility of provisioning security. Most of the studies have concentrated more on providing security than the computational cost of energy utilization. Neighbor security is proposed in this paper in addition to the existing de facto ANODR protocol for provisioning security in ANODR. The design and implementation of FB-NTT-S-ANODR to minimize energy consumption, thereby enhancing the network lifetime, are suggested. A soft computing technique for optimizing the performance of FB-NTT-S-ANODR is attempted. From experimental results, the proposed FB-NTT-S-ANODR minimizes the total energy consumption by 93.07%. Hence, the proposed method is more suitable for provisioning security and enhancing the network lifetime.
