Abstract

Low Earth Orbit (LEO) satellites are increasingly being used to provide connectivity for wide area Internet of Things (IoT) sensing applications. Distributed IoT terminals are not able to coordinate their uplink transmissions to the nano-satellites, and so operate in a grant-free mode. Quality-of-Service (QoS) depends on the transmission attempt success statistics, which are time-varying. This paper presents asymptotic analysis results that characterize the IoT terminal’s transmission success process. We show that it converges to an inhomogeneous Poisson process, in the large population regime, and characterize the time-dependent intensity as a function of the terminal location and the attempt rate scheme. We also propose three terminal attempt rate schemes that are solutions to max-min optimization problems. The performance of the proposed schemes are compared in terms of individual terminal QoS as well as the population-wide QoS distribution. Performance for various IoT applications is also presented.

低轨道卫星分布式物联网通信：QoS性能和终端尝试率方案

低地球轨道（LEO）卫星越来越多地用于为广域物联网（IoT）传感应用提供连接。分布式物联网终端无法协调其上行传输到纳米卫星，因此以无授权模式运行。服务质量（QoS）取决于传输尝试成功的统计数据，这些统计数据是时变的。本文给出了表征物联网终端传输成功过程的渐近分析结果。我们证明了它收敛于一个非齐次泊松过程，在大种群状态下，并将时间依赖的强度表征为终端位置和尝试率方案的函数。我们还提出了三种终端尝试率方案，它们是最大最小优化问题的解决方案。从单个终端的QoS和群体范围的QoS分布两方面比较了所提出方案的性能。还介绍了各种物联网应用的性能。
