摘　　要：针对边缘指挥控制平台辅助的无人机卸载任务的边缘计算系统,通过联合优化无人机飞行轨迹,无人机发射功率,计算任务卸载比率,人工噪声功率和无人机计算能力,提出了一种安全卸载方案以最大化系统的安全容量为目标.该问题涉及多个优化参数,复杂且非凸.为此,通过块坐标下降方法将该问题分解成4个子问题,利用迭代优化技术对每个子问题进行求解.仿真实验结果表明所提方案明显提高了系统的安全容量.A secure offloading scheme is proposed aiming to maximize secrecy capacity in mobile edge computing(MEC)enabled unmanned aerial vehicle(UAV)systems by jointly optimizing the flight trajectory of UAV,transmit power of UAV,offloading ratios of computation task,artificial noise(AN)power and UAV computing capacity.The problem is hard to solve since it involves multiple optimization parameters and non-convex.The problem is decomposed into four sub-problems with block coordinate descent(BCD)method,then,the successive convex approximation(SCA)technique is used to solve each sub-problem.The simulation experiment results show that the proposed scheme significantly improves the secure capacity of the systems.
