Delay Character of a Novel Architecture for IEEE 802.16 Systems

In this paper, we propose a novel scheduling architecture for IEEE 802.16 broadband wireless access network. Based on the WFQ and WF2Q which play an important role in wired network, we do more deeply research in how integrate these algorithm into IEEE 802.16. Then, a QoS architecture with WFQ algorithm is proposed. A model for our new scheduling structure is built, and the simulations are given. The results show that the delay character is improved using the proposed architecture with the new WFQ algorithm.
