Abstract :

Transmission Control Protocol (TCP) is a reliable, end-to-end transport protocol which is most widely used for data services and is very efficient for wired networks. It also performs well in wireless networks. It is the backbone protocol of most of the internet based applications. In this paper we are comp� different congestion control and avoidance techniques which have been proposed for TCP protocols like Basic TCP Tahoe, Reno, New Reno and SACK. Our analysis is on performance of the variants of TCP. In this paper we carry out performance study of four different variants of TCP to be able to classify which variant of TCP performs better in various possible scenarios. This paper describes an ns-2 based simulation analysis. By varying different parameters and congestion control mechanism we will check its effect on Throughput
