An Evaluation of Active Queue Management and TCP Congestion Control in WiFi Networks <Abstract> In Wi-Fi networks, the bufferbloat problem is critical since it affects the TCP communication's quality of service, degrading the user experience. Solutions to this problem include designing better TCP congestion control algorithms for Wi-Fi clients or introducing efficient active queue management (AQM) in Wi-Fi routers. As a result, many congestion control and AQM algorithms have been proposed in the literature. In this study, we extensively investigate the performance of congestion control-AQM algorithms in an emulated Wi-Fi network, aiming to find the best combination. More specifically, we evaluate 14 TCP congestion control and 7 AQMs. The COBALT AQM achieves the lowest delay with all the congestion control algorithms. |
