Hybrid Energy Aware Bio Inspired Technique to Improve Network Lifetime for MANETs

The main characteristic of nodes used in mobile ad hoc networks is smaller batteries. This paper represents the bio inspired hybrid approach of two techniques namely Ant colony optimization (ACO) and Firefly Algorithm (FA) to optimize the network performance. The firefly algorithm requires the timestamps of the node pairs to find the attractiveness factor. However, this technique considers only those nodes to opt for the Hello Packet forwarding procedure that are having the sufficient residual energy. Analysis of the network's performance took into account throughput, packet delivery ratio, and remaining energy. This hybridization has certainly improved the performance of the network.
