随着诸如智能电话的移动的设备的普及，许多设备通过无线局域网（WLAN）进行通信。IEEE 802.11e标准是IEEE 802.11标准的重要扩展，其专注于与任何PHY实现一起工作的QoS。IEEE 802.11e标准引入了EDCF和HCCA。这两种方案都是有用的QoS供应，以支持延迟敏感的语音和视频应用。EDCF使用竞争窗口来区分高优先级和低优先级服务。但是，它不考虑用户的优先级。在本文中，为了解决这个问题，我们提出并实现了一个基于模糊的准入控制系统（FACS）。我们进行了一些模拟，以评估所提出的系统的性能。仿真结果表明，我们提出的系统具有良好的性能。
With the popularization of mobile devices such as smart phones, many device communicate over Wireless Local Area Networks (WLANs). The IEEE 802.11e standard is an important extension of the IEEE 802.11 standard focusing on QoS that works with any PHY implementation. The IEEE 802.11e standard introduces EDCF and HCCA. Both these schemes are useful for QoS provisioning to support delay-sensitive voice and video applications. EDCF uses the contention window to differentiate between high priority and low priority services. However, it does not consider the priority of users. In this paper, in order to deal with this problem, we propose and implement a Fuzzy-based Admission Control System (FACS). We carried out some simulations to evaluate the performance of the proposed system. The simulation results show that our proposed system has good a performance.
