Admission control for VoIP traffic in IEEE 802.11 networks
Shelly Garg, Martin Kappes · 2004
In this paper, we propose a metric for measuring the utilization of an IEEE 802.11b wireless network and outline how this metric can be accurately estimated using data that is readily available in most access points. We furthermore describe how this metric can be used to perform admission control for VoIP traffic and describe experiences with a prototype implementation. Admission control for VoIP traffic in 802.11 networks is necessary since the number of simultaneous VoIP connections in a single cell of an 802.11 network is very small.
