CONCLUSION

In this paper, we investigated the problem of edge server deployment in LEO mega-constellation, and developed CSSD, a two-stage approach for small-scale placing and dynamic allocating edge servers to minimize average access latency and balance workload. We compared CSSD with two benchmarks, simulation results demonstrate that CSSD outperforms other approaches with up to 16.37% and 35.38% enhancements in terms of workload standard deviation and user service rate while maintain low access latency.

本文研究了低轨巨型星座中边缘服务器的部署问题，并开发了 CSSD，这是一种两阶段方法，用于小规模放置和动态分配边缘服务器，以最小化平均访问延迟并平衡工作负载。我们将 CSSD 与两个基准进行了比较，仿真结果表明 CSSD 优于其他方法，在工作负载标准差和用户服务率方面分别提高了 16.37% 和 35.38%，同时保持了较低的访问延迟。
