Ad hoc nodes are usually battery-powered. Thus, energy-efficiency is of paramount importance in wireless ad hoc and sensor networks. The use of directional antennae helps to reduce energy consumption by aiming the beam only to the intended target using less energy. In addition, this kind of networks have limited resources in terms of bandwidth. Thus, the use of multicast can help very much at increasing the throughput that can be obtained. Directional MIP (D-MIP) is a well-known solution to the problem of energy-efficient multicast routing with directional antennae. However, it is a centralized scheme whose applicability to these scenarios is somehow limited. Thus, we present a new distributed energy-efficient multicast protocol with directional antennae, which incorporates a localized tree reconfiguration procedure. Our simulations show that our proposed scheme (MLDP) is able to outperform the centralized scheme under a variety of scenarios and energy models.
