An Optimized Multicast Backbone Routing for Increasing Residual Energy in MANET

Background/Objectives: Due to the presence of mobility, the nodes may move out of the coverage region. Mobility of nodes causes network partition. This will lead to heavy overhead and less packet forwarding ratio. Methods/Statistical Analysis: In this research work, Residual Energy based Reliable Multicast Routing (RERMR) is proposed to increase the packet forwarding rate based on optimized multicast backbone construction. It consists of following phases. In first phase, the multicast backbone is constructed based on trustable loop and trust factors. The backbone is maintained by means of cluster group members. If the cluster head is not responding to cluster members or other cluster head, the secondary cluster leader checks whether it attains the latency threshold and announces that as a cluster head. Reliable path is calculated based on stability of links and residual energy is saved based on signal strength and distance. Results: For simulation, the network simulator tool (NS 2.34) is used. The QoS parameters and the proposed parameters are taken for analysis for performance of existing and proposed work. Based on the simulation results, the proposed work achieves better performance than previous protocols in terms of path reliability rate, network stability rate, end to end delay, end to end transmission and communication overhead.
