Optimizing TCP/IP parameters over GPRS and WLAN networks

The growth of both the Internet and mobile systems provides the way for wireless access to the Internet. Internet based applications are mostly based on a reliable transport service, TCP (transmission control protocol), which is one of the responsible for applications performance. In this paper we characterize two currently available radio access links, the general packet radio service (GPRS) and the IEEE 802.11b standards, at the IP level, and we show the effects and optimization of some TCP parameters in these networks.
