Abstract
In IEEE 802.16j standard, it defined two types of relay stations, transparent relay station and non-transparent relay station. It also defined two types of scheduling mode, distributed scheduling and Centralized Scheduling.In our thesis, we propose a hybrid distributed scheduling scheme for WiMAX system with non-transparent relay stations. First, we define a suitable priority for each connection. Additionally, in order for starvation, the priority of the connection with low priority in each category will be dynamically promoted. In resource allocation, fixed-bandwidth is used for the UGS classes, EDF scheduling algorithm is used for ertPS and rtPS classes, WFQ for the nrtPS and BE class.
