Abstract :
IEEE 802.16 standards define different service flows to better support the quality of service (QoS), but donpsilat provide related management strategies. Based on this, we propose a new management strategy which mainly includes an admission control algorithm named QBAC (QoS Based Admission Control) and scheduling algorithm named QBMS (QoS Based Multi-Level Scheduling). QBAC and QBMS are provided to grant the QoS request of different service flows. At the same time, we try to satisfy the request of real-time service flows and improve the performance of non-real-time service flows through this new strategy. Simulation results show that the performance of real-time service flows is good and the fairness of non-real-time services gets improvement compared with current strategies.
