A new management strategy of service flow in IEEE 802.16 systems

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.
