    Abstract:   在無線網路架構中的資源限制較有線網路大,在無線網路中的排程設計與網路資源管理和通訊排程有密切的關聯,妥善分配資源的排程方式可以達到提升系統效能的目的。
    IEEE 802.16j是針對原有的IEEE 802.16標準加入了中繼台結構,目的為對處在涵蓋範圍邊緣的行動台或是處在基地台死角的行動台提供服務,或是在基地台布建不易的地方使用多躍式傳遞訊息的技術。而此新結構的加入,使得原本的排程方式必須做出改變。
    Radio resource management issue in wireless network is much stricter than in backbone network. The scheduling scheme in wireless network is close to resource management, and the main purpose of scheduling is for QoS guarantee.
    In IEEE 802.16j, the new specification for relay stations which provide service for the mobile stations which are in a blind spot or infected by shadow fading. A relay station is easier to construct when the backbone network is limited for some circumstances. With the new architecture of relay stations, we have more challenges to the scheduling issue.
    In our thesis, we are going to investigate a distributed scheduling scheme for WiMAX system with non-transparent relay stations. Our proposed scheme could provide QoS guarantee and additionally enhance the QoS for real-time service.
    Simulation results show that our proposed scheduling scheme can reduce the packet average delay time and the packet average drop rate for real time service compared with other representative researches. Therefore, our research can guarantee the QoS of real time service connections.
