Abstract:

In the system of systems combat, the space information network is complex and dynamic. It is different from other networks at time and space scales, with dynamic node relation and irreversible time relation. In order to reflect the effects of these features on modeling of the space information network and analyzing of network key nodes, the temporal network is introduced and the key nodes analysis model for the space information temporal network is proposed. Firstly, under the standard operation loop, the model of operation loop based on the temporal network is given. Then, the space information temporal network model focusing on the network edge’s timeliness is proposed. Finally, from the angle of topology structure, the metrics and model of key nodes analysis based on the operation loop are constructed. The simulation results verify the efficiency of the model.
