An Energy Efficient Design for UAV Communication With Mobile Edge Computing

论文摘要

This paper considers a UAV communication system with mobile edge computing（MEC）.We minimize the energy consumption of the whole system via jointly optimizing the UAV’s trajectory and task assignment as well as CPU’s computational speed under the set of resource constrains.To this end,we first derive the energy consumption model of data processing,and then obtain the energy consumption model of fixed-wing UAV’s flight.The optimization problem is mathematically formulated.To address the problem,we first obtain the approximate optimization problem by applying the technique of discrete linear state-space approximation,and then transform the non-convex constraints into convex by using linearization.Furthermore,a concave-convex procedure（CCCP） based algorithm is proposed in order to solve the optimization problem approximately.Numerical results show the efficacy of the proposed algorithm.
