Scheme for Maximizing Secure Communication Capacity in UAV-assisted Edge Computing Networks
Aiming at the problem that user information is easy to be leaked in UAV-assisted mobile edge computing system,based on non-orthogonal multiple access(NOMA)technology,a secure communication scheme for UAV-assisted mobile edge computing system is proposed.While ensuring the minimum secure computation requirement for each ground user,the average se-cure computation capability of the system is maximized by jointly optimizing the channel coefficients,the transmit power,the computation frequency of the central processing unit,the local computation and the UAV trajectory.Due to the uncertainty of the eavesdropper location,the coupling of multiple variables and the non-convexity of the problem,successive convex approximation and block coordinate descent method are used to solve the problem.Simulation results show that compared with the benchmark scheme,the proposed scheme outperforms the benchmark scheme in terms of system secure computation performance.
