This paper proposes a new scheduling algorithm for IEEE 802.16-2005 Broadband Wireless Metropolitan Area Networks in TDD mode. Unlike most scheduling algorithm which use one QoS parameter like Maximum SusTained Rate (MST), delay or priority to take the scheduling decision, the proposed algorithm uses all these parameters plus Jitter, Minimum rate, and class type. The algorithm put all these parameters in one polynomial, that gives priority to traffic session based on its class type, priority, and its lower QoS constrains. The priority of different sessions varies in time based on system dynamics, and the expected output of the system is a fair distribution for all session, with a maximization of throughput of priority traffic.
