摘要

视频游戏、虚拟现实/增强现实等互联网应用需要高效的第五代（5G）毫米波（mmWave）蜂窝网络。传输控制协议（TCP）是网络连接的基本协议。然而，主要由于非视线（NLoS）条件等限制，TCP 在有效利用 5G 毫米波蜂窝网络的可用带宽并保持低延迟方面面临挑战。本文介绍了往返时间变化-TCP（RTTV-TCP），以提高 5G 毫米波蜂窝网络中的 TCP 性能。本文对 5G 毫米波蜂窝网络进行了仿真，以评估 RTTV-TCP 的性能，并将其与 NewReno、HighSpeed、CUBIC、Bottleneck Bandwidth 和 Round-trip propagation time (BBR)、FB-TCP（基于模糊的 TCP）等传统 TCP 变体进行了比较。结果表明，在 5G 毫米波蜂窝网络中，RTV-TCP 比这些 TCP 变体实现了更高的平均吞吐量，同时保持了相同的延迟水平。在最差的数据包错误率（PER）情况下，当缓冲区大小与带宽延迟积（BDP）相匹配时，RTTV-TCP 的性能比 NewReno 和 CUBIC 高出 208%，比 BBR 协议高出 6%。

RTTV-TCP: Adaptive congestion control algorithm based on RTT variations for mmWave networks

Internet applications such as video gaming virtual/ augmented reality necessitate efficient fifth-generation (5G) millimeter-wave (mmWave) cellular networks. The Transmission Control Protocol (TCP) is an essential protocol for network connectivity. However, TCP faces challenges in efficiently utilizing the available bandwidth of 5G mmWave cellular networks while maintaining low latency, mainly due to constraints like Non-Line of Sight (NLoS) conditions. This paper introduces Round-Trip-Time Variations-TCP (RTTV-TCP), enhancing TCP performance in 5G mmWave cellular networks. Simulation scenarios for a 5G mmWave cellular network have been conducted to evaluate RTTV-TCP’s performance, comparing it to legacy TCP variants such as NewReno, HighSpeed, CUBIC, Bottleneck Bandwidth and Round-trip propagation time (BBR), FB-TCP (Fuzzy Based-TCP). The results demonstrate that RTTV-TCP achieves higher average throughput than these TCP variants while maintaining the same level of delay in 5G mmWave cellular networks. RTTV-TCP outperforms NewReno and CUBIC by a very significant margin, demonstrating a 208% improvement compared to HighSpeed and a 6% increase compared to BBR protocol in the worst Packet Error Rate (PER) scenario and when the buffer size matches the Bandwidth Delay Product (BDP).
