All nodes in a mobile ad hoc network are usually powered by limited battery energy. The consideration of multicast lifetime in mobile ad hoc network prevents the problem of rapid depletion of node energy, thus possibly leading to the interruption of the multicast service and reconstruction of the multicast tree. We study the multicast routing in mobile ad hoc networks to extend multicast lifetime and minimize transmission cost. A heuristic genetic algorithm is presented for constructing the least-cost multicast tree with the longest lifetime. Simulation results show that the proposed algorithm is effective and efficient.
