A simple and effective priority scheme for IEEE 802.11

In this letter, we propose an analytical model for a simple priority scheme for real-time applications in IEEE 802.11 by differentiating the initial window size, the window-increasing factor and the maximum backoff stage. Saturation throughputs and saturation delays of different priority classes are derived analytically.
