针对卫星光通信易受天气干扰的问题,提出结合HAPS系统与延迟容忍网络的卫星物联网架构,可提升星地数据传输量,并评估了其投递率与缓冲区占用情况。

摘要:

数十年来,卫星为远程物联网(IoT)服务提供了支持。然而,近年来性能日益强大的传感器不断涌现,部署数量激增,导致需要通过卫星传输的数据量大幅增长。为应对这一不断增长的需求,研究人员提出了自由空间光通信系统,因为这类系统可使用大带宽的免授权频谱,实现高数据速率。但光通信极易受到天气引发的中断影响,从而限制了其巨大潜力。本文提出将高空平台站(high altitude platform station, HAPS)系统与延迟容忍网络技术结合使用,与传统地面站网络架构相比,可提升从卫星向地面传输的数据量。研究从投递率和缓冲区占用率两方面对该架构方案进行了评估,并在后续讨论中分析了其优势、挑战以及未来研究的潜在方向。

英文摘要:

For decades, satellites have facilitated remote internet of things (IoT) services. However, the recent proliferation of increasingly capable sensors and a surge in the number deployed, has led to a substantial growth in the volume of data that needs to be transmitted via satellites. In response to this growing demand, free space optical communication systems have been proposed, as they allow for the use of large bandwidths of unlicensed spectrum, enabling high data rates. However, optical communications are highly vulnerable to weather-induced disruptions, thereby limiting their high potential. This paper proposes the use of high altitude platform station (HAPS) systems in conjunction with delay-tolerant networking techniques to increase the amount of data that can be transmitted to the ground from satellites when compared to the use of traditional ground station network architectures. The architectural proposal is evaluated in terms of delivery ratio and buffer occupancy, and the subsequent discussion analyzes the advantages, challenges and potential areas for future research.
