Current IEEE 802.11 standards are not capable of offering Quality-of-Service (QoS) guarantees to WLAN users. This is mainly due to some gaps existing in their MAC protocol. Even the QoS features of the new extension, IEEE 802.11e draft standard, do not suffice. It still needs connection admission control techniques to avoid saturating the wireless medium and service differentiation in order to fairly and efficiently share the available resources when it comes to packet (or frame) scheduling. The main goal of this work is to introduce two essential ingredients, connection admission control and packet scheduling, in the MAC protocol of IEEE 802.11 WLANs in order to actually offer QoS guarantees to their users. This is essential if multiple services, with diverse QoS requirements, are to be offered in such networks
