Abstract

We present an analytical framework to model the send- ing queue of an IEEE 802.11 EDCA wireless station that uses the TXOPlimit MAC parameter to send more than one packet in each transmission opportunity. An application of this model to the estimate of packet delay from the num- ber of packets received at the AP in each transmission is presented. This method is well suited to be deployed in an infrastructured WLAN but can be used for any wire- less communication based on the EDCA access mechanism. Its main advantage is that it requires neither modifications to the MAC protocol nor cooperation of the wireless STAs. The approach suitability to predict the delay of real time VoIP calls is validated through simulation.
