Abstract
Ability to find a low-energy broadcast routing quickly is vital to a wireless system’s energy efficiency. Directional antennae save power by concentrating the transmission towards the intended destinations. A routing is given by assigning a transmission power, angle, and direction to every networking unit, and the problem of finding such a power saving routing is called the Directional Minimum Energy Broadcast Problem (D-MEBP). In the well known Minimum Energy Broadcast Problem (MEBP), the transmission angle is fixed to 2π. Previous works suggested to adapt MEBP algorithms to D-MEBP by two procedures, Reduced Beam (RB) and Directional (D). As the running time of the routing algorithms is a critical factor, we reduce the time complexity of both by one order of magnitude.
