摘　　要：具有通信链路多跳、时断时续等特征的无人集群网络已广泛应用于协同态势感知等作战场景。面向不同场景选择合理的网络架构,对进一步提升通信性能、保障任务实施具有重要意义。现有网络架构性能分析主要针对稳态场景且未综合考虑资源调度与路由机制影响,在通信链路时断时续的无人集群作战场景中适用性不足。针对集中式与分布式两类网络架构,综合考虑节点密度、网络跳数、链路中断概率影响,建立了集中式与分布式网络架构下业务时延及最优化模型,搭建了面向协同任务的无人集群网络化仿真平台并进行仿真,提高网络架构适用性分析准确度,给出了不同参数下的最优网络架构选择。模型与仿真结果表明,在网络跳数较少、网络节点密度较大时集中式网络架构性能更优,反之更倾向于选择分布式网络架构;同时,集中式网络受链路中断概率影响更大。Flying ad hoc network(FANET)with multi-hop and intermittent links has been widely used in collaborative situational awareness and other scenarios.Choosing optimal network architecture in different scenarios is crucial to developing communication performance and ensuring mission implementation.The state-of-the-art mainly focuses on steady-state scenarios without comprehensively considering the impact of resource scheduling and routing mechanisms,resulting in insufficient applicability in FANET with multi-hop and intermittent links.The service delay and optimization model under centralized and distributed network architectures are constructed,considering the parameters such as node density,network hop,and outage probability of links.Besides,the FANET simulation platform based on collaborative tasks is built,and simulation experiments are carried out,which can improve the accuracy of network architecture performance analysis.The numerical and simulation results show that the centralized network performs better with low network hop and large node density;otherwise,the distributed network is preferred,and the centralized network is more affected by the link outage probability.
