| Abstract(in English) | The Quality of Service (QoS) of both-way real-time applications over a Wireless Local Area Network (WLAN) is frequently degraded due to the packet loss at the buffer of the access point (AP), which is in turn caused by the congestion at the IEEE802.11 MAC layer. Thus, the performance analysis of real-time applications over WLANs needs to take into account both the occupancy of the AP buffer and the congestion level of the IEEE802.11 DCF with non-saturated nodes. In this paper, we provide an analytical model for IEEE802.11 WLANs, which combines a queueing model for accounting the AP buffer occupancy and an Markov chain model for accounting the congestion of the IEEE802.11 DCF. We use the proposed model to evaluate how many Voice over IP (VoIP) flows can be multiplexed over an WLAN without loss of any packets. |
