【摘要】：针对卫星网络拓扑结构的时变特征,通过构建时变拓扑图序列模型,将卫星时变拓扑网络分解为一系列具有稳定状态的拓扑图结构。综合考虑节点在网络中的全局性影响和局部性影响,以节点介数、节点紧密度和节点距离的重要度贡献为度量参数,提出了稳态卫星网络节点重要度评估方法,设计了卫星时变网络节点重要度评估算法,通过典型实例验证了算法的准确性和有效性。实验结果表明,该方法能够有效地区分卫星时变网络节点重要度差异,准确评价卫星节点对卫星网络资源的控制能力。
[Abstract]:According to the satellite network topology time-varying characteristics by constructing time-varying topology sequence model, the time-varying satellite network topology is decomposed into a series of steady state topology structure. The global effect of influence of the nodes in the network and the local comprehensive consideration of in betweenness, the important contribution of nodes close distance and the node as the metric, presents the steady-state satellite network node importance evaluation method, network node importance evaluation algorithm design of the satellite, through typical examples verify the correctness and validity of the algorithm. The experimental results show that this method can effectively distinguish the time-varying satellite network node important degree difference, accurate evaluation the ability to control satellite nodes on the satellite cyber source.
