Abstract
In this paper, we propose a new wireless scheduling algorithm for the IEEE 802.11e HCF. The algorithm grants the mobile stations variable time for the upstream data flow in proportion to the queue size of the transmission buffer. At the same time, it retrieves half of the extra time allocated in previous cycle from those flows whose requirement has stopped. Hence, the system achieves stability by preventing the ping-pong phenomena. The algorithm is computationally simple, and as compared to the other algorithms, it gives bounded delays and jitter to the real-time applications under heavy load conditions.
