    • 在支援終端用戶行動能力的IEEE 802.16e無線都會網路中，電池能量是行動節點(Mobile Station, MS)的重要資源，如何設計MS節能機制使其能有效延長連續工作時間是非常重要的議題。因此在IEEE 802.16e網路重負載(Heavy Load)的環境中針對非即時(Non-Real Time)訊務設計出有效率的節能機制，是本論文的研究主題。
    　　在本篇論文中，我們設計動態能量管理(Dynamic Energy Management, DEM)機制，本動態能量管理機制除了可以讓基地台(Base Station, BS)或MS較容易掌握提出休眠之時機外，亦可降低MS頻繁的狀態切換進而達到節能的效果。我們利用封包聚集的概念設計排程方法，考慮網路傳輸控制協定(Transmission Control Protocol, TCP)的傳輸特性並改善IEEE 802.16e標準規範中針對非即時訊務所定義休眠類別一(Class 1機制)之休眠方式。接著我們利用MS估測伺服器壅塞視窗大小(Congestion Window Size)以及BS所計算出排程時間相關參數，由BS給予MS適當的休眠參數。本論文以檔案傳輸協定(File Transfer Protocol, FTP)應用為例，並且只要是TCP傳輸方式之應用皆可套用我們提出之DEM機制。由模擬結果可以看到，吾人提出之DEM機制與Class 1機制比較後，針對不同的非即時訊務量，除了可以減少平均耗電量約16%~25%，同時也可減少狀態切換率63%~77%。
