摘　　要：为了在WLAN标准IEEE802.11e中高效、高质量地传输各类业务,以及保证业务之间的公平性,提出一种基于自适应信道预留的接纳控制算法。算法中首先采用资源共享的方法提前为业务预留适当的信道资源,使用信道利用率作为接入准则,当网络资源不足时采用自适应地调节已经接入业务流的服务质量来满足新请求的业务流的服务质量需求。结果表明,该算法保证了各业务之间的公平性以及服务质量需求,而且最大程度地接入了更多的业务流,提高了网络的整体性能。In order to transmit traffics in high efficiency and quality and ensure fairness between traffics,this paper proposed the adaptive channel reservation based-admission control algorithm. Firstly,this algorithm took resource sharing to reserve suitable channel resources for traffics and used channel utilization as the admission control rule. When the network resources were not enough,took the adaptive mechanism to adjust QoS of the admitted flows in order to meet the new flow as much as possible. The results show that the algorithm ensures fairness between traffics and their QoS requirements,and admits more flows while increasing the throughput of the network.
