Abstract-The node importance evaluation of network is of great significance for the improvement of power communication network's reliability. At present, the indexes used in the node importance evaluation in power communication networks are usually one -sided. Dealing with this, this paper presents a multiindex based node importance evaluation method. In this method, degree centrality, betweenness centrality and eigenvector centrality are employed as indexes, and fuzzy clustering method is adopted to classify network nodes, to finally obtain the set of important nodes. The method can be applied to the evaluation of node importance in power communication network. The experiment reflects the effectiveness of the method.
