The Study of Routing and Handover in NGSO Rosette Constellations

摘要

摘要: 该文讨论了具有星际链路的非静止轨道玫瑰星座中的路由与切换，在深入分析其网络拓扑变化持性的基础上，提出了一种新的路由策略循环刚新路由策略．随后，将切换过程与路由有机结合，提出了最小跳数切换策略．计算仿真结果表明，与已有的策略相比，该文提出的策略能够获得较低的传播延时和较小的切换频率，具有很好的实用价值．

Abstract: This paper discusses the routing and handover issue hi the NGSO rosette satel-lite constellations equipped with Inter-Satellite Links (ISL). Based on the variation regular-ity of the rosette constellation topology, a novel routing strategy named circularly refreshing routing strategy is proposed. Then, by appropriately combining routing and handover pro-cedure, the Minimal-Hop Handover (MHH) strategy is proposed. Compared with other previous strategies, the simulation results show that MHH strategy performs better with less propagation delay and lower handover frequency, so it has a good practical value.
