Abstract: Find the central node in satellite network can help us balance traffic flow in satellite network and improve its robustness. Currently, most of centrality measures of network are based on un-weighted graph or weighted graph with only edges weights, which cannot be used in analyzing information centrality in satellite network directly. This paper presents a novel satellite network model with weighted nodes and weighted edges, and the weights vary with satellite network topology, information acquired by satellites and traffic flow in inter-satellite link. Based on the satellite network model, we give three different measures, which are information acquisition centrality, information betweenness centrality and information eigenvector centrality, to determine the central node under different conditions. Finally, we simulate a satellite constellation, establish its weighted model and analyze its information centrality. The results show that the model and measures can be used to determine the information central node in satellite network effectively.
