Abstract

The invention provides a hyperedge-based time evolution diagram design method suitable for a satellite-ground network. The method comprises the following implementation steps: constructing a topological structure of the satellite-ground network; constructing a topological matrix A of the satellite-ground network; obtaining a hyperedge set J, a communication arc set W and a storage arc set Z of the satellite-ground network; and drawing a hyperedge set J-based time evolution graph. According to the method, the time-varying characteristics of calculation, communication and storage resources in the satellite-to-ground network are represented through the correlation of the hyperedge presentation node space, and the method is used for solving the technical problem that the complexity of multi-dimensional time-varying resource management by the satellite-to-ground network is relatively high in the prior art.
