Different Mechanism for Improving TCP Performance Over Wireless Links
Overview Most of the data transfer applications like FTP, web transactions use TCP/IP, the internet end-to-end transfer protocol. TCP has been tuned for traditional networks comprising wired links and stationary hosts. It assumes congestion in the network to be the primary cause for packet losses and unusual delays, and adapts to it. The TCP receiver sends cumulative acknowledgments (ACKs) for successfully received segments, which the sender uses to determine which segments have been successfully received. The sender identifies the loss of a packet either by the arrival of several duplicate cumulative ACKs, triggering a fast retransmission, or by the absence of an ACK for a timeout interval equal to the sum of the smoothed roundtrip delay and four times its mean deviation.
