Problems solved by technology

The problem with the node deletion method is that if the deletion of multiple nodes makes the network disconnected, then the importance of these nodes will be consistent, making the evaluation results inaccurate
At the same time, there are still some shortcomings in the node contraction method, mainly including: there is no way to evaluate symmetrical nodes, and it is not easy to control the contraction range of general nodes

Abstract

The invention relates to a method for evaluating the importance of nodes in a communication network, and belongs to the technical field of node analysis in the network. The method for evaluating the importance of the nodes in the communication network comprises the following steps: (1) establishing a mathematical model of a weighted network according to the actual communication network, (2) respectively calculating basic indexes, including a node degree k, a node betweenness b, a feature vector index Ce and a compactness index Cc, of the weighted network, conducting normalization, (3) conducting linear combined weighting on an F1, an F2, an F3 and an F4 to obtain a final score F of a comprehensive evaluation, (4) ranking the n nodes according to the value of the final score F of the comprehensive evaluation, using the nodes in the higher rank as the important nodes in the actual communication network, and therefore determining the importance of the nodes in the actual communication network. According to the method for evaluating the importance of the nodes in the communication network, firstly, the bandwidth is utilized for weighting the actual communication network, and then ranking of the importance of the nodes is achieved through the comprehensive evaluation.

Description

technical field [0001] The invention relates to a communication network node importance evaluation method, which belongs to the technical field of node analysis in the network. Background technique [0002] With the rapid development of communication and information technology, the coverage of communication network is gradually expanding, and the business carried by it is gradually increasing, and its role in modern large-scale network systems is becoming more and more important. At the same time, the number of nodes in the communication network will continue to increase, and its complexity will continue to increase, so it is still necessary to study the importance of nodes in the communication network. In recent years, the evaluation methods for the importance of complex network nodes mainly include: [0003] (1) Based on the connection between the node and other nodes: the simplest way is to use the degree of the node as the measure of the importance of the node. It is co...
