摘要：
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 proposed for LEO satellite networks. The proposed protocol not only reduces the routing computation and storage overheads, but also provides good routing survivability under random satellite failure. The experimental results confirm our conclusions. © 2015, Springer Science+Business Media New York.
