Performance Evaluation of TCP over WLAN 802.11 with the Snoop Performance Enhancing Proxy

Chi-ho Ng, Jack Chow

Open publisher page 17 citations

Abstract

The growing popularity of wireless devices used to access the Internet and an increasing use of the TCP/IP protocol suites, indicate that in the near future TCP protocol will be frequently used over the wireless links connecting wireless devices. The characteristics of wireless links are significantly different from characteristics of wired network links because data is frequently lost due to the volatile environment in which wireless links operate. TCP was originally designed for wired networks, where loss of data is assumed to be due to congestion only. This assumption leads to poor performance of TCP in a wireless environment. Hence, various mechanisms were proposed to improve TCP performance over wireless links. One such mechanism is a performance enhancing proxy, such as the Snoop protocol.
