A scheduling algorithm for providing real-time guarantees in 802.11e WLANs

In this paper we propose a scheduling algorithm for supporting quality of service (QoS) in an IEEE 802.11e network using the HCF controlled channel access (HCCA) function. The algorithm consists of an offline procedure that generates a service schedule over a base period, and an online procedure that applies the latter to actually schedule transmission opportunities to HCCA flows.
