Abstract :
This paper starts with detailing the IEEE 802.16 network architecture and the quality of service (QoS) architecture; followed by a network utility function, which is related to the average queuing delay of each subscriber station (SS); and then a dynamic bandwidth allocation (DBA) algorithm is proposed. This algorithm takes into consideration the QoS requirements of different traffic types and makes use of a utility function to minimize the average queuing delay. Simulation results have shown the efficiency of the DBA.
