Paper Abstract

Throughput estimation of users in a wireless packet data communication system utilizing the General Packet radio Service (GPRS) is investigated in this work. GPRS allows dynamic allocation of the bandwidth to a mobile terminal according to its traffic demand, which results in better resource utilization and a lower communication cost. The proposed user throughput estimation scheme relies on packet data traffic modeling. Since future wireless data services are mainly in web browsing, we consider a traffic model for today's WWW traffic that consists of ON/OFF two states with the ON period containing a sequence of document transmissions. A realistic traffic model is derived based on actual traffic data measurements. The throughput and transmission delay for fixed coding schemes can be obtained accordingly. This research effort contributes to the capacity planning of GPRS for its data services.
