Abstract In this paper, we propose a novel centrality called connected dominating centrality according to the real-life demand analysis. The connected dominating set of a network has two characteristics, connectivity and dominance. Based on the two characteristics, we recursively construct the connected dominating sets of the induced dominating sub graphs and generate a directed spanning tree with dominating relationships. By combining the number of nodes dominated by a node, its hierarchical level in the directed spanning tree, and the weights of the edges which connect the dominator and its dominated nodes, we define the calculation formula of our proposed connected dominating centrality. To verify the effectiveness of the centrality, an experiment is made on the paper co-author network of an international journal. The experimental results show that the nodes with higher connected dominating centrality constitute the backbone network and can maintain the shape of network well. Some of them bridge different research communities; others are the kernels of communities. They have good ability in organizing and controlling the network.
