We consider the problem of minimizing the energy consumptions of a given multicast connection in mobile ad hoc networks (MANETs) that use omnidirectional antennas and have limited energy resources. Unlike most multicast algorithms that use centralized greedy algorithms to achieve energyefficiency in static ad hoc networks, our distributed algorithms explore the localized operations to take the advantages of power saving offered by the wireless multicast advantage property in mobile networks. The extensive simulation results have shown that our DMEM (Distributed Minimum Energy Multicast) algorithm is very efficient in terms of energy saving under different node motilities.
