Smart Mobility Applications Supported by Non-Terrestrial Networks: Addressing the Need for Low Per-Packet Delays

Low Earth Orbit (LEO) satellites offer a promising solution for ubiquitous connectivity and can be utilized in 5G Non-Terrestrial Networks (NTNs) for applications like IoT, autonomous driving, and rural communication. They are particularly suited for smart mobility in urban environments, where fast data transmission and real-time control of vehicles and infrastructure are crucial. In this study, we compare TCP protocols for satellite communication in smart mobility scenarios and propose a solution that uses a limited buffer size to reduce per-packet delays without affecting the throughput.
