Abstract:

An adaptive-energy-threshold-based energy-efficient on-demand multicast routing protocol (EMRP) for wireless Ad Hoc and sensor networks is proposed to prolong the network lifetime. Based on the network energy status, EMRP adaptively calculates an energy threshold which protects the nodes with low remaining energy by discouraging their engagement in multicast tree. Further, it adopts destination-driven strategy to efficiently reduce the multicast tree size to save the energy for a multicast task. EMRP does not require nodes to keep global or local network state information. It has low overheads and is easy to implement. Simulation results show that EMRP greatly reduces the energy cost for per-packet delivery and prolongs the network lifetime.

Key words: wireless Ad Hoc and sensor network, energy-efficient multicast, energy threshold, destination-driven, on-demand multicast routing
