Performance Evaluation of Uplink Delay-Tolerant Packet Service in IEEE 802.16-Based Networks
The authors provide an analytical model for efficient dynamic capacity allocation in IEEE 802.16 wireless metropolitan area network, where the non-real-time traffic can utilize the bandwidth unused by the real-time traffic. They investigate the uplink delay of the nrtPS service flow as a function of the capacity allocations for the rtPS (ertPS) and UGS service flows. Unicast polling is applied for the bandwidth reservation of the nrtPS and rtPS (ertPS) packets. Their analysis accounts for both reservation and scheduling delay components.
