Many devices communicate over Wireless Local Area Networks (WLANs). The IEEE 802.11e standard for WLANs 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 high priority and low priority services. However, it does not consider the priority of users. In order to deal with this problem, in our previous work, we proposed a Fuzzy-based Admission Control System (FACS). In this paper, we present the effect of client priority in the performance of a Fuzzy-based WLAN Triage system. We concluded that when CKT, RSSI and UP values increase and NP value decreases, the clients have high priority, so they will keep connection to the AP.
