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).
