A wireless ad hoc network consists of mobile nodes that are powered by batteries. The limited battery lifetime imposes a severe constraint on the network performance, energy conservation in such a network thus is of paramount importance, and energy efficient operations are critical to prolong the lifetime of the network. All-to-all multicasting is one fundamental operation in wireless ad hoc networks, in this paper the authors focus on the design of energy efficient routing algorithms for this operation. Specifically, they consider the following minimum-energy all-to-all multicasting problem.
