| Abstract | In IEEE 802.16 systems, the algorithm of admission control (AC) is very important in guaranteeing the Quality of Service (QoS) and managing service flows. However, the IEEE 802.16 standards do not specify any related strategies or algorithms on AC. In order to improve the system performance and satisfy the QoS of stations to the max, we propose a new AC strategy, which includes a weighted blocking rate based priority strategy and a satisfaction-degree based bandwidth-borrowing strategy named SDB in this paper. The simulation results show that the proposed strategy improves the overall performance of system in terms of weighted blocking rate. Furthermore, our strategy enhances the QoS in comparison with the strategy adopting conventional bandwidth-borrowing algorithm. |
