基于互信息的通信网络节点重要性度量方法
Evaluation Method for Node Importance in Communication Network Based on Mutual Information
摘要
Abstract
The intentional attacks on the nodes makes the complex network very fragile under information condition,so it is very important to explore accurately and then protect these core nodes in the network.Based on analyzing the characteristics of communication network under the special condition,and taking the definition method of "amount of information" in the information communication system for reference,this paper propose a new evaluation method that are suitable for the directed-weighted networks.Through the comparative analysis of this method and the existing methods in small-scale mixed weighted network,the validity and advantage of this method is verified.The mixed weighted network evolution model based on BBV(Barrat-Barthelemy-Vespignani) is established,and the simulation which to evaluate the node importance in the generated large-scale communication network is performed.The experiment analysis results show that the proposed method may evaluate the node importance more easily and effectively than that of the state of the evaluation method.关键词
