摘　　要：为避免由于网络节点发生故障而导致重组或网络崩溃的情况发生,提出一种空间物联网信息的k连通拓扑控制算法,通过研究空间物联网信息的体系结构对其进行建模,并采用泊松分布设定模型的原始状态通信半径和节点数量参数,根据分簇权重的能量平衡、信道质量、节点故障和移动性准则对其进行优化,完成节点、标识与未标识邻域节点的度值对比,最后采用睡眠调度策略达到网络运行延长和拓扑结构稳定的目的。经过仿真表明,上述算法在空间物联网信息中,形成的簇相对稳定,有效地延长了网络的工作周期,而且优化了网络的连通性。In order to avoid recombination or network collapse caused by network node failure,this article proposed a k-connected topology control algorithm for spatial IoT information.It was modeled by researching the architecture of spatial IoT information.Poisson distribution was used to set the original communication radius and the number of nodes in model,and the model was optimized based on the energy balance of clustering weight,channel quality,node failure,and mobility criteria,so as to compare the values of nodes,identified neighborhood nodes and unidentified neighborhood nodes.Finally,the sleep scheduling strategy was adopted to extend the network operation and stabilize the topology.Simulations show that the cluster formed by the proposed algorithm in the spatial IoT information is relatively stable.The working cycle is effectively extended and the network connectivity is optimized.
