A Utility-Based Dynamic Bandwidth Allocation Algorithm in IEEE 802.16 Networks to Minimize Average Queuing Delay

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.
