摘要

毫米波技术可以提供非常高的数据速率，是5G通信的关键推动因素。然而，毫米波信号的穿透损耗大，各向同性传播差，导致间歇性丢包。TCP的拥塞控制算法将丢包视为网络拥塞的隐式通知，并通过降低数据传输速率来做出反应。在本研究中，我们研究了TCP的拥塞控制算法如何影响毫米波链路上可实现的数据速率。我们使用诸如拥塞窗口大小(cwnd)、吞吐量、往返时间(RTT)和信噪比(SINR)等指标来讨论不同TCP版本的性能。

Analysis of Transport Layer Congestion Control Algorithms over 5G Millimeter Wave Networks

The Millimeter Wave technology can provide very high data rates and is a key enabler of 5G communication. However, mmWave signals suffer with high penetration loss and poor isotropic propagation which causes intermittent packet losses. TCP's congestion control algorithms consider packet loss as an implicit notification of network congestion and react by reducing the data transmission rate. In this research we examine how TCP's congestion control algorithms impact the achievable data rate over mmWave links. We discuss the performance of different TCP versions using metrics such as congestion window size (cwnd), throughput, Round Trip Time (RTT), and Signal-to-Interference-plus-Noise Ratio (SINR).
