摘　　要：针对无人机在无线通信网络场景中的保密通信和飞行过程中保证安全节能问题,提出了一种多目标优化设计方案。基于无人机通信模型、无人机能耗模型和环境限制模型构建了无人机调度和航迹规划问题(USPOP)的多目标优化模型,以无人机无线通信的平均保密率、无人机悬停能耗和无人机飞行能耗3个目标为优化目标进行优化,并通过改进的第三代非支配排序遗传算法对问题进行求解。仿真结果表明,本文改进算法能有效解决构建的优化问题,并且相对于其他对比算法有更好的收敛效果。Aiming at the problem of UAV secrecy communication and ensuring safety as well energy saving during flight in the wireless network scenario,a multi-objective optimization scheme was proposed.The scheme mainly includes UAV transmission model,UAV energy consumption model and environmental constraints model,and further constructs the multi-objective optimization model of UAV scheduling and path optimization problem(USPOP),which optimizes average communication secrecy rate of UAV wireless communication,UAV hovering energy consumption and UAV flight energy consumption.Then,a non-dominated sorting genetic algorithm Ⅲ(NSGA-Ⅲ) with discrete normal distribution initialization,differential mechanism,genetic mechanism and avoiding obstacles operator(NDGA-NSGA-Ⅲ) is proposed to solve USPOP.Simulation results show that the proposed algorithm can effectively solve the constructed optimization problem,and the convergence effect is better than other comparison algorithms.
