Abstract
This paper studies a unmanned aerial vehicle (UAV)-enabled wireless relay communication system, where a UAV provides relay services to a source node and a destination node. To minimize the total power consumption of UAV, we jointly design the trajectory of UAV and transmission power of both UAV and source node, under the constraints on minimum data rate, transmission power, UAV’s mobility, and information-causality. The obtained problem is non-convex and difficult to solve in general. Hence, a successive convex approximation based optimization method is proposed to solve the problem approximately. Numerical simulations are performed to show effectiveness of the proposed method.
