Hardware-in-the-loop simulation system for space information networks

Thanks to the recent advances in SIS (Space Information Science) and increasingly mature technologies, network simulations have attracted much attention, which play vital roles in research on validation of the correctness of SIN's (Space Information Network) solutions. In this paper, we constitute an architecture of a hardware-in-the-loop simulation system, where we use a server to act as a real satellite of SINs. Moreover, we model the channel of the satellite network relying on real cables and servers by referring to the Corazza model. Furthermore, based on the data of real weather events, we propose a coordinate mode for reducing LEO's (Low Earth Orbit) communication delay and validate the efficiency of our proposed method on simulation platform by simplifying the problem to a shortest path problem.
