Abstract

The recently approved IEEE 802.11e standard improves the support for real-time multimedia applications in Wireless LANs. Yet, to provide some level of guarantee in terms of QoS parameters, it is essential to use an admission control scheme. We have devised one such scheme, which bases the admissibility test on the time occupancy of the medium. The network state is assessed through an analytical model of the EDCA in non-saturation conditions. In the paper, beyond describing the proposed scheme, we also show its effectiveness in the case of voice over IP applications.
