Traditional TCP Congestion Control Algorithms Evaluation in Wired-cum-Wireless Networks: A performance evaluation of wired-cum-wireless networks

摘要

Congestion control algorithms exist for decades to prevent package loss in intense traffic networks. Several solutions developed over the years tried to solve this problem, including the creation of new algorithms. However, hybrid wired and wireless networks, or wired-cum-wireless, common in modern days, bring new challenges to programmers and engineers who try to overcome the numerous new problems that this kind of network presents. This work carries out a performance comparison, in a wired-cum-wireless network, using TCP congestion control algorithms variants: New Reno and CUBIC. The comparison is to determine which of those algorithms performs better in several situations, like multiple disconnections caused by mobility, interference and congested links. The results showed that the CUBIC is a more stable and fair algorithm, but it has a significantly less data flow than New Reno.
