Abstract :
The WiMAX technology based on IEEE 802.16 is expected to support multimedia services with guaranteed quality of service (QoS). In this paper, a scheduler structure with priority classes is designed for IEEE 802.16 wireless networks, and a channel quality dependent rate-limited (CD-RL) algorithm is proposed. CD-RL provides promised data rates while taking throughput into account. With a carefully designed "order changing" method, CD-RL can be implemented with low complexity, which makes it feasible in practical systems. Simulation results reveal that CD-RL has good performances in fairness, minimum reserved traffic rate and average packet delay.
