Reliable and energy efficient hybrid multicast routing in Mobile Ad Hoc Networks

摘要

In this paper, the balance of energy-reliability trade off is considered with respect to hybrid multicast routing for self organized MANETs (Mobile Ad Hoc Networks) applications. Our scheme Reliable and Energy Efficient Hybrid Multicast Routing Protocol (REHMRP) operates in the following phases. (1) Computation of Node Remaining Energy (NRE) and power level by applying designed energy model. (2) Determining the node Reliability Decisive Factor (RDF) based on power level of a node, signal strength, and node mobility. (3) Pruning neighbor nodes that have Reliability Decisive Factor, Remaining Energy (RE) less than the predefined threshold value. (4) Discovery of multipath multicast mesh of routes using route request and reply packet. (5) Chooses best path from mesh of paths for data transmission based on Path Reliability Decisive Factor (PRPF), and (6) Route maintenance against negative Reliability Factor (RF), link and node failures. Performance evaluation have been done in NS-2 against packet delivery ration and end-to-end delay. Simulation results shows that our proposed scheme REHMRP outperforms Zone Routing Protocol (ZRP) and Multicast Zone Routing Protocol (MZRP).
