Position aware energy efficient multicast routing in MANET

Recently multicast routing protocols become increasingly important aspect in mobile adhoc networks(MANETs), as they effectively manage group communications. In this paper, we address the scalability problem of multicast routing protocols to support energy efficient paths over MANETs. In this paper a new position based energy efficient multicast routing protocol is introduced. Here the network area is divided into the equal sized hexagonal cells. For each cell, cell head(CH) is elected. In this novel approach cell head backup is elected only if the cell contains any multicast member. Our approach reduces the energy constraint by choosing the cell head, cell head backup and forwarding nodes based on the highest battery capacity. The protocol also increases the lifetime of the node and network. Simulation results show that PAEEM provides higher packet delivery ratio and provides less energy consumption compared to PBQMRP protocol.
