无人机辅助的移动边缘计算任务卸载策略
UAV assisted mobile edge computing task offloading strategy
摘要
Abstract
In the application scenario where the access point cannot access the mobile device due to ground signal blocking or shadow,an unmanned aerial vehicle(UAV)-assisted mobile edge computing system model based on simultaneous wireless information and power transfer is constructed by correctly deploying and operating the UAV.In this model,the UAV not only provides mobile edge computing(MEC)services for the mobile device as an air base station,but also offloads the computing tasks of the mobile device to the AP as a relay.In order to optimize the total energy consumption of UAV,a UAV-assisted MEC task offloading strategy is proposed.Firstly,the strategy constructs the problem model by jointly optimizing the UAV horizontal position,communication and computing resources and task division ratio.And then,in response to the non convex nature of the problem,a joint optimization algorithm based on successive convex approximation is designed to obtain the suboptimal solutions.The simulation results verify the feasibility and effectiveness of the proposed UAV-assisted MEC task offloading strategy and joint optimization algorithm.关键词
