Modeling for dimensioning and configuring general packet radio service networks

This paper presents an analytical model that enables network dimensioning and configuration investigations for a general packet radio service (GPRS) network. The model accounts for transmission control protocol (TCP) using a detailed mathematical representation and introduces a ´TCP factor´ metric and procedure to model TCP behavior. The analytical model results, for a web browsing application, are validated by means of discrete event simulation. The ability of the analytical model to perform accurate network dimensioning and admission control is also demonstrated.
