TCP FOR WIRELESS WORLD

TCP FOR WIRELESS WORLD

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 affectivity and
Practicality) on the proposals. From our analysis, we present conclusions on what are the
most optimum end-to-end and link-layer techniques.
