Abstract
This paper presents a quasi-dynamic inter-satellite link (ISL) reassignment method to optimize the snapshot routing performance for LEO (low Earth orbit) satellite networks. When the snapshot routing tables are switching in all satellites, we propose to reassign the inter-plane ISLs regularly to improve the quality of the next snapshot. Evaluation results indicate that our method can obtain invariable and longer snapshot duration, which is superior to the natural partition method. Meanwhile, compared with the equal partition method, the proposed method can averagely increase 5.95 % on-board transceiver utility ratio. We believe that our method could be practically and effectively applied in future LEO satellite networks.
