Joint Optimization of Placement, Beamwidth, and Power Allocation in the UAV-Enabled Network

Abstract

In this paper, we consider an unmanned aerial vehicle (UAV)-enabled network in which a UAV equipped with a directional antenna relays data from a ground base station (GBS) to ground users (GUs). Under this system, we study a problem minimizing the weighted sum power consumption of the GBS and the UAV by jointly optimizing the location of the UAV, beamwidth of the directional antenna, and power allocation. To solve the problem, we develop a simple heuristic algorithm, and verify its effectiveness through simulation results.
