A dynamic queue assignment algorithm under IEEE 802.11e

Paper improved dynamic queue assignment algorithm cross - layer optimization unequal protection under IEEE 802.11e was proposed. In this algorithm, queue AC[1] and AC[0] were utilized to transmit video frame. Queue priorities, which were utilized to map with video frame priorities, were calculated accord to queue status. The proposed algorithm assigned a queue for a video flame according to the priority of the frame and the congestion conditions of different queues. The simulation results show that video distortion can be greatly decreased by using the proposed algorithm.
