Abstract

For the application scenario that unmanned aerial vehicle-based aerial base station provide communication for residents in disaster areas, energy-efficient optimization of unmanned aerial vehicle algorithm under QoS of users constraints (EEOA) is proposed in this paper. It aims to maximize the energy-efficient of UAV under QoS of users constraints. Users transmit data to UAV in non-orthogonal multiple access way. The UAV uses continuous interference cancellation technology to decode the messages of each user.Firstly, energy-efficiency optimization function under QoS of users constraints is constructed. Then, the objective function is about height of UAV through mathematical transformation. Finally, the optimal height of UAV is obtained by bisection method. The simulation results show that the proposed EEOA algorithm effectively improves the energy efficiency compared with the equivalent orthogonal multiple access (OMA) algorithm.

Key words： unmanned aerial vehicle; energy-efficient; non-orthogonal multiple access; successive interference cancellation; bisection method
