Vol: 48(62) No: 1 / March 2003 Modeling Resource Allocations Techniques for GPRS/EGPRS Networks D. Todinca Department of Computer Engineering, University Politehnica of Timisoara, Faculty of Computer and Control Engineering, Bd. V. Parvan 2, 1900 Timisoara, Romania, phone: (40) –256-4032, e-mail: todinca@cs.utt.ro Keywords: GPRS, EGPRS, resource allocation, scheduling algorithms. Abstract This article presents an overview of the research efforts concerning resource allocation techniques in data transfer over mobile networks, placing our work in the context of the domain. We put an emphasis on the modeling and simulation techniques used for GPRS and EGPRS networks and we present our simulation model, which maintains a balance between simplicity and the capability to describe and simulate many different aspects concerning performance issues in (E)GPRS networks.
