Techniques to Improve TCP over Wireless Links
Abstract:
There has been an increase in importance
in supporting data applications over networks with both wireless and wireline
links. Many standard data applications used in current wireline networks
are based on the reliable Transmission Control Protocol (TCP) which has
been proven to work well in traditional networks where packet losses are
mainly due to network congestion. However, TCP performance gets severely
affected when used in wireless links where the channel is typically characterized
by random errors due to fading and shadowing. There have been many
schemes proposed to improve the performance of TCP over networks that have
high-BER wireless links. In this paper, we discuss the end-to-end
schemes and link-layer schemes that have been proposed and simulated by
various authors and we give analytical reviews (based on effectivity and
practicality) on the proposals. From our analysis, we present conclusions
on what are the most optimum end-to-end and link-layer techniques.
