面向任务的空间信息网络关键节点分析模型
A task-oriented analyzing key nodes model of spatial information networks
摘要
Abstract
In order to mine the key nodes in the spatial information network in the real task scenario and protect them,based on the mission tasks undertaken by spatial information network in the context of system,node types and information flow rela-tionships are distinguished with the help of operational ring theory.Considering the high dynamic nature of spatial information network,time-varying graph analysis method is used to model the network.Based on the spatial information dynamic network model,the value factor of the operational ring is given by considering the formation time of the operational ring and combi-ning with the traditional complex network indicators,the importance evaluation index of the spatial information network nodes is proposed as time-varying ring betweenness.The effectiveness and rationality of the proposed method are verified by compa-ring the node importance under indexes of time-varying ring betweenness,degree centrality and number of operational rings through experimental simulation.关键词
