Once deemed a far-fetched vision, emerging deployments of massive satellite constellations will soon offer true global coverage. When these constellations overlay the evolving terrestrial networks, a new hybrid continuum is formed which has the potential to provide uninterrupted coverage. In this paper, we provide an analytic framework for the uplink coverage probability in hybrid satellite-terrestrial networks. The framework extends well-developed terrestrial models that utilize tools from stochastic geometry by incorporating an additional layer that fits the emerging next generation satellite-terrestrial networks. The paper captures the impact of both (i) the constellation size, and (ii) the terrestrial base station density on the coverage of the uplink traffic which is dominant in applications relying on wireless sensor networks, such as the Internet of Things. This framework provides insights that guide the design of hybrid network infrastructures for a desired quality of service.

在混合卫星地面网络中模拟上行链路覆盖性能

一旦被视为遥不可及的愿景，大规模卫星星座的新兴部署将很快提供真正的全球覆盖。当这些星座覆盖不断发展的地面网络时，就会形成一个新的混合连续体，有可能提供不间断的覆盖。在本文中，我们为混合星地网络中的上行链路覆盖概率提供了一个分析框架。该框架扩展了成熟的地面模型，这些模型利用随机几何中的工具，通过加入一个适合新兴的下一代卫星-地面网络的附加层。本文捕捉了 (i) 星座大小和 (ii) 地面基站密度对上行链路流量覆盖的影响，上行链路流量在依赖无线传感器网络的应用中占主导地位，比如物联网。该框架提供了指导混合网络基础设施设计的洞察力，以获得所需的服务质量。
