Analysis of TCP Variant Protocol Using Active Queue Management Techniques in Wired-Cum-Wireless Networks (original) (raw)

Advances in intelligent systems and computing, 2017

Abstract

In this work, we analyzed the performance of TCP variant protocols in wired-cum-wireless networks considering active queue management (AQM) techniques such as random exponential marking (REM) and adaptive virtual queue (AVQ) along with Droptail. For analysis, we consider Reno, Newreno, Sack1, and Vegas as TCP variants and proposed a network model for wired-cum-wireless scenario. Then, the performance of TCP variants is analyzed using delayed acknowledgement (DelACK) technique. The simulation results show that Newreno performs better than others when DelACK is not used. However, when DelACK is used, the performance of Vegas is better than others irrespective of AQM techniques.
