An optimized SGL routing algorithm design in satellite communication

Based on the analysis of communication process between satellite and ground data center, the bi-level intersected architecture of Satellite-Ground Link (SGL) network was constructed. An optimized SGL routing algorithm for this architecture was proposed. This algorithm could find out optimizing communication links between satellite and ground data center passing through several ground data relay nodes, taking account of data buffer constraint at each data receiver. The effectiveness and efficiency of this algorithm have been tested by simulations at the end.
