A study of radio resource cost for TCP
2001 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

Enhancements to the GSM system such as GPRS and EDGE introduce several new services like full external network access. Communication solutions using an end-to-end protocol affect the total network performance and raises questions about how effective the radio resource is used. TCP commonly used over Internet is of special interest. This thesis investigates how effective an EGPRS radio resource is exploited for a non-real-time service based on TCP. The performance is monitored in terms of radio channel waste, radio usage-ratio and the experienced throughput. For the purpose, a model of a TCP controlled application is proposed and built in MATLAB. The performance is studied under different radio-channel statistics, shadow-fading correlation time intervals and different quality Internet connections. The outcome of the study shows an increased amount of observed timeouts for shadow-fading correlation times of the same size as the round-trip time. Otherwise the overall TCP performance over the EGPRS radio-link is comparable with TCP performance over a non-wireless communication-link with equal bandwidth.
