Some investigations on improving the performance of tcp in adhoc networks

Abstract

Transmission Control Protocol TCP is a transport layer protocol newlinewhich provides reliable end to end data delivery between end hosts in newlinetraditional wired network environment In TCP reliability is achieved by newlineretransmitting the lost packets Thus each TCP sender maintains a running newlineaverage of the estimated round trip delay and the average deviation derived newlinefrom it Packets will be retransmitted if the sender receives no newlineacknowledgment within a certain timeout interval eg the sum of smoothed newlineround trip delay and four times the average deviation or receives duplicate newlineacknowledgements Due to the inherent reliability of wired networks there is newlinean implicit assumption made by TCP that any packet loss is due to newlinecongestion To reduce congestion newline newline
