Abstract :
The goal of this paper is to investigate the efficiency of different algorithms used for resource allocation in data transfer over EGPRS networks. The focus is on the efficiency during congested periods in order to ensure reduced file transfer delay. A number of algorithms are presented for the resource allocation, and some generic mathematical results are presented for a two coding system. Simulation is relied on to produce results for the algorithms and it is found that iterative round robin (IRR) and oldest queue (OQ) produce the best results. These are then proposed to be good candidates for implementing transmission control.
