Conclusion

This paper studied the design of satellite-ground topology to enable low-latency transmission in emerging LEO SNs. We formulated the Low-latency Satellite-Ground Interconnecting (LSGI) problem for minimizing the maximum transmission latency while keeping stable routing and high network reachability. We then proposed a coordinated satelliteground interconnection algorithm, called CSGI, in distributed GSes. Comprehensive experiment results demonstrate that our algorithm outperforms related algorithms.

本文研究了面向新兴低轨卫星网络（LEO SNs）的星地拓扑设计问题，旨在实现低时延传输。我们构建了低时延星地互连（LSGI）问题，其目标是在保持路由稳定与高网络可达性的同时，最小化最大传输时延。进而，我们提出了一种在分布式地面站（GSes）中运行的协同式星地互联算法（CSGI）。全面的实验结果表明，我们所提出的算法在性能上优于相关算法。
