Low-Load Survivable Routing Protocol for LEO Satellite Networks

Abstract: In this paper, we put forward the methods of footprint shift and separation for the virtual topology model of LEO satellite networks, which can reduce the effects of the Polar Regions and cross-seam inter-satellite-links (ISLs) on the virtual topology and improve the utilization of ISLs. Furthermore, a low-load survivable routing protocol called Virtual Snapshot Routing Protocol is p…
