空间信息网络关键节点分析方法研究

Study on Key Nodes Analysis Method of Space Information Network

空间信息网络结构具有动态变化等特性,对其关键节点分析应该在某一时间段内考虑。在基于时间片的空间信息网络关键节点分析方法基础上,结合卫星的业务特点,提出了一种基于累积模式的动态空间信息网络关键节点分析方法,通过对节点之间访问时间和访问次数的加权处理,将空间信息网络转化为加权静态空间信息网络后进行关键节点分析。利用STK和MATLAB软件进行仿真,实验结果表明所提出的方法能较好地分析空间信息网络关键节点。

Because of the dynamic of the Space Information Network(SIN),the key nodes analysis should be considered in a time section.The method of the key nodes analysis of SIN was introduced based on time slice.On this basis,combining with the features of satellite,a new method of the key nodes analysis of SIN based on accumulation pattern was proposed.The new method used the weighted processing technology to the access time and the access number,and then transformed the SIN to a static weighted network.Through the simulation using STK and MATLAB,the results of experiments show that the proposed method could analyze the key nodes effectively.
