宽带无线接入系统中基于QoS和带宽的接纳控制方案研究

Research of QoS and Bandwidth-Based Admission Control Scheme in IEEE 802.16e System

针对以前的接纳控制方案只考虑带宽和速率的不足,提出了新的接纳控制算法,该算法综合考虑带宽和延时要求,并针对特定业务使用了动态带宽预留和动态QoS方案,在保证QoS的同时提高了带宽利用率。

Because the admission control schemes proposed before take only bandwidth and rate requirement into consideration, a new admission control scheme is proposed in the paper which take both bandwidth and delay into consideration. According to the different characters of services, an adaptive bandwidth reservation and QoS scheme is introduced to increase the efficiency of bandwidth while guaranteeing different QoS requirement of different services.
