Multimedia applications over IEEE 802.11 wireless LANs (WLANs) such as wVoIP have recently attracted the focus of many researchers. Unlike best-effort applications, multimedia applications are delay- and/or bandwidth-sensitive. In order for these applications to achieve an acceptable QoS, the network must provide them with certain QoS guarantees. This paper proposes an admission control heuristic for applications with delay requirements in IEEE 802.11e EDCA WLANs. To develop the proposed heuristic, we first derive an analytical approximation of delays experienced by packets when delivered via IEEE 802.11e EDCA WLANs. We validate the heuristic through simulations of voice traffic.
