摘　　要：针对无人机辅助通信网络频谱效率亟待提高的问题,提出了认知无人机网络的混合决策中继选择算法,构建切换容忍和时延容忍的设计方案。通过时延信息确定候选中继簇,使其具备最佳通信条件的节点,完成数据传输,获得中断概率性能的提升,解决阴影区域链路切换可靠性过低的问题。仿真结果表明:与传统单参数决策方案相比,在不同接入策略下其中断概率分别下降30%和33%。For improving the spectrum efficiency of unmanned aerial vehicle( UAV)-assisted communication networks,a hybrid decision-making relay selection algorithm for cognitive UAV networks was proposed. The switch tolerance and time delay tolerance design method was constructed. The candidate relays based on delay information was determined. The nodes had the best communication conditions to complete data transmission,obtain an improvement in the performance of the outage probability,and solve the problem of low reliability of link switching in the shadow area. The simulation results show that compared with the traditional singleparameter decision-making scheme,the outage probability of the proposed scheme is reduced by 30% and 33%respectively under different access strategies.
