Energy Efficient Multicast Routing in Mobile Ad Hoc Networks

The Mobile Ad hoc Networks playing critical role in network aided communication requirements. The features such as ad hoc and open architecture based connectivity and node mobility are elevating the mobile ad hoc networks as much as feasible to deploy and use. The direct communication between any of two nodes in this network is possible if target node is in the range of source node. If not, the indirect communication took place, which is usually referred as multi hop routing. The multi hop routing occurs as either a unicast model (one source node to one destination node), multicast model (one source node to multiple destination nodes) or multiple casting (manifold unicast routing). In these routing strategies, provision of service quality in multi hop routing is a challenging task. The optimal quality of service in routing, magnifies the delivery ratio, transmission rate, network life span and other expected characteristics of the ad hoc routing. Among the quality service provision factors minimal energy conservation is prime factor, which is since the nodes involved in routing are self-energized and if discharged early then the route will be destructed that causes discontinued routing. The energy consumption is more specific in multicast routing, hence it is grabbing the more attention of the current research contributions.
