| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 96 === In the system of WiMAX，different transmission rate , allocate bandwidth and other QoS parameters can be provided to different kind of service .It is important to provide optimum QoS transmission for different application and efficacious bandwidth resource control for the WiMAX system.
In WiMAX system, each connection is assigned with different number of slots in one frame. These numbers will be decided by the BS when the connections are set up. The assigned slots in one frame will satisfy the basic requirement of each connection. When all the connections have been assigned as required, there might be some slots of the frame left. In our paper, the left slots can be reassigned to all the connections with our protocol. In this rearrangement, each class of service flow will get fixed ratio of the left slots. The gained slots in this round will be distributed evenly to the connections of the same class.
