为挖掘复杂网络中的关键节点及提高网络鲁棒性,针对有/无线多网融合的层级网络,提出了动态融合复杂网络模型及其节点重要度评估方法.结合动态融合复杂网; 络的特点,定义了边连通概率、路径连通概率、网络连通概率、融合节点比例、融合节点分布和融合路径比例等与网络动态性和融合性相关的参数.在单层复杂网络; 节点重要度评估指标的基础上,设计了融合网络节点度中心性、节点介数中心性和节点融合中心性指标.其中,融合节点的节点融合中心性表示融合节点对网络融合; 的贡献程度,非融合节点的节点融合中心性表示非融合节点对网络融合的辅助作用程度,主要体现在作为融合节点之间的中继节点.最后,综合考虑网络拓扑结构、; 动态融合特性等因素进行节点重要度评估.以改进的动态交织风筝网络为例进行仿真分析,结果表明该方法能够比较全面地刻画节点在动态融合复杂网络中的重要性; .利用NS2搭建由光通信网和卫星通信网融合构成的仿真实验网络,进一步验证了在仿真网络环境中本方法的有效性.

To seek key nodes and improve network robustness,the dynamic convergence; complex network model and its node importance evaluation method are; proposed for wired and wireless integrating layered networks.; Considering characteristic of dynamic convergence complex networks,; parameters including edge connection probability, path connection; probability, network connection probability, convergence node; proportion, convergence node distribution and convergence path; proportion are designed. Based on node importance evaluation indexes in; single-layer complex networks,the node degree centrality,node; betweenness centrality and node convergence centrality in dynamic; convergence complex networks are presented. Node convergence centrality; of convergence nodes indicates their contribution to network; convergence,and that of non-convergence nodes indicates their auxiliary; effect to network convergence,especially they are used as relay nodes; among convergence nodes. At last,node importance evaluation is; implemented considering network topology structure and its dynamic; convergence characteristic. Typical example results of improved dynamic; convergence kite networks show that the proposed method can; comprehensively depict the node importance in dynamic convergence; complex networks. Simulation network composed of fiber communication; network and satellite communication network is designed by NS2,further; indicating the effectiveness of the proposed method.
