An analysis of the channel utilization for call admission control in voice over WLAN
Huanxu Pan, Yamano Satoru · 2006
In this paper, we present an analytical method for effectively evaluating the channel utilization of voice calls in voice over WLAN systems. The method is under realistic assumptions general enough to deal with various cases of mixed traffic sources and transmission conditions. The accuracy and effectiveness of our method are validated through experiments. The method provided a basis for a prototype call-admission-control system for VoWLAN, in an attempt to enable an operational VoWLAN system with quality-of-service support.
