Energy-Efficient Full-Duplex UAV Relaying with Trajectory Optimization and Power Control in Maritime Communication Environments
文献摘要：
This paper solves an energy-efficient op-timization problem of a fixed-wing unmanned aerial vehicle(UAV)assisted full-duplex mobile relaying in maritime communication environments.Taking the speed and the acceleration of the UAV and the information-causality constraints into consideration,the energy-efficiency of the system under investiga-tion is maximized by jointly optimizing the UAV's trajectory and the individual transmit power levels of the source and the UAV relay nodes.The optimiza-tion problem is non-convex and thus cannot be solved directly.Therefore,it is decoupled into two sub-problems.One sub-problem is for the transmit power control at the source and the UAV relay nodes,and the other aims at optimizing the UAV's flight trajec-tory.By using the Lagrangian dual and Dinkelbach methods,the two sub-problems are solved,leading to an iterative algorithm for the joint design of transmit power control and trajectory optimization.Computer simulations demonstrated that by conducting the pro-posed algorithm,the flight trajectory of the UAV and the individual transmit power levels of the nodes can be flexibly adjusted according to the system condi-tions,and the proposed algorithm can achieve signif-icantly higher energy efficiency as compared with the other benchmark schemes.
