Study of Transmission Control Protocol (TCP) performance over Non-Terrestrial Networks (NTN)

In an increasingly interconnected world, the demand for high-speed, low-latency internet access is constantly growing. Non-Terrestrial Networks (NTNs) have emerged as a promising solution to provide global connectivity to remote and underdeveloped areas, as well as to complement existing terrestrial...
