Tcp Reno, Sack And Vegas Performance Analysis

Abstract

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.
