Since the lack of considering energy consumption in wireless ad hoc networks makes it easy to exhaust battery energy and result in partitioning of the entire network, power-aware multicasting is proposed to reduce power consumption. In this paper, we study the quality of service (QoS) multicast routing in ad hoc networks. It is an NP-complete problem. We present an energy-efficient genetic algorithm mechanism to resolve these problems. The proposed genetic algorithm depends on bounded end-to-end delay and minimum energy cost of the multicast tree. Simulation results show that the proposed algorithm is effective and efficient.
