基于作战环的空间信息网络动态建模

Dynamic modeling of spatial information network based on operation ring

针对空间信息网络的使命任务和本身的高动态性、复杂性等特点,提出一种空间信息网络建模方法。通过作战环理论区分网络节点和边的不同类型,在时间累积时变图的基础上对网络建模。使用STK软件构建案例网络,分析空间信息动态网结构特性,研究空间信息动态网中作战环的形成过程以及节点之间的联系,通过作战环的数量以及网络连通性能的变化结果验证了模型的可用性。相较于其他网络模型,所提方法能够同时反映空间信息网络的功能性和高动态性,有效体现网络节点和边的特征属性。

Specific to the mission of spatial information network and its characteristics of high dynamic and complexity,a modeling method of spatial information network is proposed.The functional attributes of nodes and edges of the network are distinguished by the operational ring theory,and the network is modeled on the basis of the time-cumulative time-varying graph.STK software is used to build a case network,analyze the structural characteristics of the spatial information dynamic network,and study the formation process of combat rings in the spatial information dynamic network and the connections between nodes.The availability of the model is verified by the changes in the number of combat rings and the connectivity performance of the network.Compared with other network models,the proposed method can reflect both the functionality and high dynamics of spatial information networks,and effectively reflect the characteristics of network nodes and edges.
