Behavioral study of TCP Tahoe, Reno, New-Reno Vegas, and Lite

Comparing to wired networks, there are many different characteristics in wireless environments, such as higher error rate, longer delay, lower bandwidth, frequent mobility and so on, which makes TCP congestion control mechanisms not directly suitable for wireless networks, and many improved TCP congestion control mechanisms have been presented. The main goal of these mechanisms was to successfully manage congestion, reliably handle loss, and minimize transmission errors. In this paper, we analyze and compare the different congestion control and avoidance mechanisms which have been proposed for TCP/IP protocols, namely: Tahoe, Reno, New-Reno, Lite, TCP Vegas and SACK. Study of these variants provides guidelines for improved congestion and corruption control in mobile ad-hoc network
