Abstract

In this paper, a novel hierarchical packet scheduling model for IEEE 802.16 uplink is proposed based on J. Bennett & H. Zhang scheduling model [1]. The soft-QoS traffics introduced in this new model together with hard-QoS and best-effort traffics are scheduled by the Base Station (BS). The model can distribute bandwidth reasonably between the QoS and the best-effort traffics. It also guarantees the validness and fairness among the QoS traffics. We give the analytical delay comparison between two models and evaluate the performance by simulations.
