Wafa Elmannai, Abdul Razaque, Khaled Elleithy

TL;DR
This paper introduces TCP-UB, a new congestion-aware TCP variant combining features of TCP Westwood and Vegas, designed to improve performance in mobile wireless networks, especially under high congestion and mobility.
Contribution
The paper presents TCP-UB, a novel TCP variant that integrates Westwood and Vegas features, and demonstrates its improved stability over existing variants in congested, mobile scenarios.
Findings
TCP-UB outperforms Vegas and Westwood in stability under congestion.
TCP-UB shows better performance in mobile wireless environments.
Simulation results confirm TCP-UB's robustness in high congestion scenarios.
Abstract
Transmission control protocol (TCP) is a connection oriented protocol for several types of distributed applications. TCP is reliable particularly for traditional fixed networks. With emergence of faster wireless networks, TCP has been performing poorly in its original format. The performance of TCP is affected due to assorted factors including congestion window, maximum packet size, retry limit, recovery mechanism, backup mechanism and mobility. To overcome deficiency of original TCP, Several modifications have been introduced to improve network quality. The mobility is a major hurdle in degrading the performance of mobile wireless networks. In this paper, we introduce and implement new TCP variant University of Bridgeport (UB) that combines the features of TCP Westwood and Vegas. We examine the performance of TCP-UB, Vegas and Westwood using different realistic scenarios. NS2 simulator…
