A novel measure of centrality based on betweenness

Zhichao Song, Hongtao Duan, Yuanzheng Ge, Xiaogang Qiu

Abstract

The centrality of a node is a crucial indicator to understand how important this node is in a network, and several measures of centrality have been used to realize the identification. In this paper, we propose a new one named load centrality based on the betweenness changes caused by the removal of some nodes in the network. This measure of centrality combines the ideas: more important node is closer to others and more important node stands between more node pairs. By comparing with the other point centrality measures, the load centrality is validated further.
