Wireless access networks such as IEEE 802.16 employ a multi-rate physical layer. Such physical layer designs rely on a user-defined link adaptation mechanism that changes the coding and modulation schemes, thus the transmission rate, in order to maintain link reliability at a desired level under different channel conditions. The multirate operation has a significant effect on the fairness of the services...
In this paper, we propose a novel cross layer scheduling strategy for IEEE 802.16 WMAN. The proposed scheduler will first guarantee all the prescribed QoS requirements, then take into account different wireless channel conditions obtained by subscriber stations to enhance the system throughput while it ensures the property of the fairness per connection. The performance of our scheduler is evaluated...
