通信网络中关键节点的选取方法研究

Research on Selecting the Key Nodes in Communication Network

近年来,随着复杂网络研究的不断兴起,作为复杂网络研究的一个重要分支,复杂网络关键节点的发现研究的重要性也日益突出。例如要攻击一个通信网络,就要找到通信网络中的关键节点。本文基于节点的度和接近度两个指标,建立了选取通信网络关键节点的模型,利用这种模型Zachary网络进行了研究,用Matlab得到了Zachary网络的节点的重要程度排序。

Recently, with the continuous rise of the study of complex networks, as an important branch of the study of complex networks, the study of key nodes discovery has become more and more important. For example, we should find the key nodes of communication network before attacking them. In the paper, based on the node degree and closeness, the model of selecting the key node of a communication network is established. Then the model is used to study Zachary network. Finally, the important sort of the node of the Zachary network is found by the Matlab simulation.
