    Abstract: IEEE 802.16相關標準已經發展出像是已經成熟的802.16d、支援移動性的802.16e還有支援Multihop Relay (MR)的802.16j。802.16j的特點就是多了可以轉傳資料的Relay Station (RS),藉由RS可以擴大網路覆蓋範圍(coverage extension)並提升系統傳輸效能(throughput enhancement),不過也因此使得802.16j的topology不同於以往,變成類似Tree的架構,傳輸路徑也不再是單純的single hop,有可能變成two hop甚至multihop的方式,也因此產生了新的多重路徑(multipath)問題:BS和MS中間的路徑不再唯一,因此路徑也需適時的配合改變,否則可能會嚴重的影響效能。
    本文以連線的QoS(Quality of Service)要求為標準,依照系統中delay需求順序建立連線BS與RS間的連線,最後建構出系統的tree topology並依此進行傳送。目的在讓高QoS連線與BS間的Hop數降低,達到降低delay並穩定jitter的目標,並提供congestion control。最後利用NS-2網路模擬器對不同的網路環境進行模擬,測試所產生的效能並進行評估,以驗證此方法的實際可行性。
