Delay-sensitive video transmission over IEEE 802.11 wireless local area networks (WLANs) is analyzed in a cross-layer optimization framework. The effect of delay constraint on the quality of received packets is studied by analyzing “expired-time packet discard rate”. Three analytical models are examined and it is shown that M/M/1 model is quite an adequate model for analyzing delay-limited applications...
Cross-layer optimization has been recently proposed for improving the performance of real-time video transmission over 802.11 WLAN. In this paper, an improved IEEE 802.11 WLAN analytical model under unsaturated traffic conditions was proposed. It adapts Distributed Coordination Function (DCF) models to handle all the states. Two special states were added for this model, one is the idle state, which...
