摘　　要：集群通信网络具有拓扑时变,节点移动性强,链路状态不稳定等特点,难以维持稳定的拓扑结构。网络被分割为互不连通的子群体,为了解决不同群体间的通信问题,将协同中继节点引入,提出一种动态感知的连通恢复方法。搭建协同通信模型,推导出链路质量指标的数学表达;设计多目标链路评价函数,通过多目标连通恢复算法实现最优的中继位置规划。仿真结果表明:在不同信道环境下,该算法能够在2个非连通群体间获得最优中继位置,恢复网络连通。The cluster communication network has the characteristics of time-varying topology, strong node mobility, and unstable link status, etc. It is difficult to maintain a stable topology. The network is divided into disconnected subgroups. In order to solve the communication problem between different groups, the cooperative relay node is introduced and a dynamic-sensing connection recovery method is proposed. A cooperative communication model is built and the mathematical expression of link quality indicators is deduced, which designs a multi-objective link evaluation function and achieves the optimal relay location planning through a multi-objective connectivity recovery algorithm. Simulation results show that the proposed algorithm can obtain optimal relay position between two disconnected groups and restore the network connectivity under different channel environments.
