摘要

為了滿足無線寬頻存取的需求，針對無線都會網路的 IEEE 802.16e Standard 已經在 2006 年制訂完成。在無線網路的環境中，電力是很重要且珍貴的資源，所以 IEEE 802.16e 定義了一套省電機制來節省電力消耗。但是當一個行動用戶所建立的連線越來越多，此機制就沒有辦法更有效率的使用電力。為了解決這個問題，這篇論文提出了一個 Adaptive Wake-up Mechanism，改善在一個行動用戶同時建立多條連線時電力使用的效率，透過一個簡單但是正確的系統模擬，顯示出我們提出的省電機制能夠有效率的使用電力，並且不影響傳輸的資料量，進而在 IEEE 802.16e 網路中建立一個高能源效率的傳輸模式。

To meet the requirements of wireless broadband access, IEEE 802.16e for wireless metropolitan network supporting mobility has been standardized in 2006. Since power
consumption is a critical issue for wireless mobile networks, IEEE 802.16e defines the power saving mechanism for more efficient energy usage. However, the power saving
mechanism of IEEE 802.16e cannot achieve expected energy efficiency for the mobile station with multiple connections. To solve this problem, we propose an adaptive power saving mechanism to increase the energy efficiency for IEEE 802.16e mobile station with multiple connections. A simple but accuracy system model is also presented for
validating our simulations. The simulation result shows that the proposed mechanism achieves higher energy efficiency without sacrificing the throughput. With the proposed scheme, the high energy-efficient communication is obtained in IEEE 802.16e networks.
