Energy Efficient Clustering Technique for Multicast Routing Protocol in Wireless Ad Hoc Networks

Vol. 7  No. 8  pp. 74-81


Energy efficient communication in mobile ad hoc networks (MANET) is a very stringent issue due to the power-constraint of battery in each mobile node. Therefore, designing a suitable energy efficient multicast routing protocol to conserve power as much as possible while still achieving good system performance is a challenge. This paper proposed an energy efficient clustering technique (EECT) for multicast routing protocol, which each node uses weight cost function based on the transmission power level, residual power and node speed to form cluster in the neighboring area and the node with the minimum weight value is selected as the clusterhead. The EECT can alleviate the energy consumption because the communication between clusterhead and member is adjustable with appropriate power level. The tree-based MAODV and the mesh-based ODMRP ad hoc multicast routing protocols are adapted to the EECT being executed on the each clusterhead. Simulation results demonstrate the adaptation of MAODV and ODMRP using EECT have better system performance than MAODV and ODMRP in terms of total energy consumption, mean end-to-end delay, mean hop count, packet delivery ratio and percentage of alive nodes for different multicast group size and mobility.
