摘要

本論文提出一個在連結適應移動式微波存取全球互通網路環境下新式的連結無線通訊資源管理方式和針對差異性服務提出階層式優先權佇列排程演算法。無線通訊資源管理方法可重新分配突發屬性及動態調整各使用者的頻寬分配以增進資源的使用率。而所提出的階層式優先權佇列排程演算法使用階層式之排程架構，並針對各別的資料流型態使用適當的排程演算法。更進一步來說，此方法獨立針對多點傳播之服務品質保證來探討。模擬結果顯示所提出的方法可以得到較低的延遲時間，較好的頻寬使用率和較高的吞吐量。

This paper proposes a novel radio resource management scheme in the link adaptive WiMAX network and the hierarchical priority-queuing with weighted round-robin (HPWRR) scheduling algorithm for differentiated services. The radio resource management scheme can re-assign the burst profile and dynamically adjust the allocated bandwidth to the SSs to improve the resource utilization. Then, the HPWRR scheduling algorithm uses the multi-levels hierarchical scheduling architecture and uses different scheduling algorithms fit to each traffic type, respectively. Furthermore, the multicast session is considered as the new traffic type in the proposed scheme to guarantee the Quality of Service (QoS) requirements. Simulations show that the proposed methods can get lower delay, better bandwidth utilization and higher throughput.
