Backoff-based priority schemes for IEEE 802.11

Backoff-based priority scheme for IEEE 802.11 are achieved by differentiating the minimum backoff window size, the backoff window-increasing factor, and the maximum backoff stage. An analytical model is proposed to study the performance of backoff-based priority schemes in terms of saturation throughput and saturation delay. Simulations are conduced to validate the analytical results. Results of this paper are beneficial in designing good prioritized QoS parameters.
