Topology structure design and performance analysis on distributed satellite cluster networks

In this paper, an investigation into the topology structure design and performance analysis the distributed satellite cluster network (DSCN) in space information networks (SINs) at geosynchronous orbit (GEO) is presented. Use of concepts of domains, strong/weak link, hubs, small world, and degree realizability by employing Network Science Theory is examined for a fifteen-node DSCN. The impacts of the concepts are analyzed. The simulation results validate the effectiveness of the proposed concepts and show that the hybrid architecture realizes a stunning trade-off between the network efficiency and robustness.
