“…Also one can see that the performance of TCP Vegas is similar to TCP Sack at 0.001 error rate. From figure 2 it can be observed that for low error rates (0.0001), TCP Vegas is slightly less efficient than others, but as the error rate increases (0.1) TCP Vegas emerges as the better option [9].…”

In this paper, two TCP variants are compared in different scenario. 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. Our analysis is on performance of TCP variants. In this paper we carry out performance study of TCP Sack and TCP Vegas 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.

“…Ghassan in 2012 suggested a slightly modern version of TCP named as TCP Vegas with a difference in basic congestion avoidance algorithm from that of TCP Reno (Ghassan et al, 2011). Another modified form of TCP Reno is the TCP Sack that is capable of addition of selective acknowledgements to TCP (Waghmare et al, 2011). For the sack of clarity and as a consequence of this research, it is proposed that simple modifications to bandwidth estimation during congestion avoidance phase of TCP Westwood considerably improves network's congestion control as well as metrics such as Throughput and Goodput.…”

Congestion control in networks is prioritized for maintaining high and error free data rates. The work in this paper directly investigates possible attainment of optimized TCP congestion control over wired networks through a proposed modification done to one of the existing TCP protocols. Firstly, the proposed approach looks into various queue limits e.g. Drop Tail and RED. Evidently, a comparison of these two queue limits vividly demonstrates that RED demonstrates a better performance when it comes to attainment of optimized TCP congestion control. This investigation is naturally followed by simulating different TCP versions such as TCP Tahoe, TCP Sack, TCP NewReno, TCP Reno and TCP Westwood for checking and comparing their effective resource utilization such as network Throughputs, comparative bandwidths, retransmission rates and window sizes. Simulations in this regard were carried through using NS-2 (Network Simulator-2) simulation software. From simulation results, as evident in this paper, TCP Westwood was found to be the best candidate for innovation out of the mentioned flavors based on its output performance. The most active objective of the proposed research presented in this paper was to modify the already chosen TCP Westwood protocol and to come up with a new variant of it proposed here namely as "TCP New-Westwood" for providing a higher degree of TCP congestion control.

“…But multimedia applications can tolerate errors to a limited extent and retransmitted packet is of little use. TCP Reno [3] is a modified version of the basic TCP protocol. TCP Reno requires immediate receiving of acknowledgment whenever a segment is received.…”

TCP is the most widely used transport protocol by the Internet community. It is used by applications e-mail, WWW, and file transfer. TCP provides reliable transfer of stream of bytes between a pair of processes.There are different TCP implementations and each modifies the basic congestion control mechanismslightly. The sender reaction to congestion is different. But all the TCP implementations are originally designed and tuned to wired networks.Their working in wireless networks is an area of interest to researchers. Mobile networks like adhoc networks pose more challenges to the researchers. In this paper we do the performance analysis of TCP implementationsTCP Reno, TCP SACK and TCP Vegas in adhoc networks.Different mobility scenarios are considered. The metrics considered are Throughput, End-End delay, Packet delivery ratio and Jitter. NS-2.35 is used as simulator.
