A Method for Ranking the Importance of Command and Communication Network Nodes Based on Complex Networks

In order to address the issue of node importance ranking in command and communication network, the basic principles of complex networks were adopted to propose two basic models: unweighted undirected networks and weighted undirected networks. Three typical structures, namely tree, grid, and hybrid structures, were established, and the importance of nodes is comprehensively quantified using four indicators: degree centrality, betweenness centrality, connectivity, and network efficiency. The experiment shows that the ranking method proposed in the paper can accurately and efficiently identify important nodes, providing a reference for the application and guarantee of command and communication network.
