CEMAODV: Cross-layer Design of Energy-conserving Multicast AODV Routing Protocol

Energy conservation is a critical issue in wireless ad hoe networks, as usually nodes are powered by batteries only. This paper proposes a Cross-layer design of Energy-aware Multicast Ad hoc On-Demand Distance Vector (CEMAODV) routing protocol. At me hand it adopts cross-layer mechanism and energy-aware metric to modify AODV routing protocol to reduce the energy consumption of the route to construct a source-based tree. At the other hand the inherent broadcast property of wireless network is utilized to optimize the initial multicast tree by orienting a node's parent to another tree node and pruning some tree members if necessary, The result of the simulation shows that CEMAODV can outperform MAODV, reducing the consumed energy by about 70% and average delay to about half. And the performance is better when the multicast group is large in the network.
