A NEW MEASURE OF CENTRALITY IN COMPLEX NETWORKS BASED ON SUB-TREE

摘要：

How to evaluate nodesimportance in networks and detect the centrality has become a vital problem in improving the efficiency of telecommunication and making a disease immunity strategy. We consider the mechanisms of real networks, and define a cost function to different hierarchies of node sub-trees to measure the importance of a node. This method takes a nodes influence in local networks and global together to evaluate the contribution of a node in the efficiency. The results of a classical networks show this method is proper to describe nodes difference in a network, and detect the centrality.
