Energy Efficient Positioning of Flying Base Stations via Coulomb’s law

In this paper, we propose an algorithm for an initial positioning of the unmanned aerial vehicles (UAVs) acting as flying base stations (FlyBSs). We target to maximize the FlyBSs deployment efficiency in terms of the number of users satisfied with an experienced data rate and the energy consumed by the FlyBSs to fly to their initial positions. The required data rates of the users, energy consumption of the FlyBSs, and mutual interference among all base stations and users are represented as electrical forces and the initial positions of the FlyBSs are determined via Coulomb's law. In comparison to the state of the art algorithms, the efficiency of the FlyBS deployment is improved at least 2.5 times and, at the same time, the users' satisfaction with the experienced data rate is increased between 6 to 10 %.
