  • IEEE 802.16e 無線都會型網路新增了對於行動用戶站 (Mobile Station)之存取支援後,如何延長行動用戶站之工作時間變成熱門探討議題,IEEE 802.16e 是利用將行動用戶站進入睡眠模式來達到能源節省的目的,而針對不同服務類型之連線, 標準訂定了三種能源節省類型規範,其中能源節省類型I適用於非即時性服務連線 (Non-Real Time),然而同一行動用戶站中, 可能同時存在非即時性連線、即時性連線 (Real Time)及管理連線,因此若僅考慮單一服務連線類型並不能反映出行動用戶站內之真實連線情況,應將其他連線類型納入考量。
    在這篇論文中, 我們設計了一睡眠規劃機制,利用事件發生之預測值來做為能源節省類型I之睡眠區間規劃建議,並同時考量了當即時性連線及管理連線與非即時性連線併存之情形,
    利用同步的方式將睡眠區間最大化達到能源節省之最大效益,同時亦有效降低封包服務延遲之時間。


    The IEEE 802.16e wireless metropolitan area network provides broadband wireless access for mobile stations (MSs). How to prolong mobile station operation time is an issue receiving much attention. In order to achieve this purpose, the specified in the IEEE 802.16e provide sleep mode operation to make mobile station state switch to sleep state to conserve power. Because of different QoS required, the IEEE 802.16e define 3 type of power saving classes for sleep mode to utilize. Power saving class of type I is recommended for non-real-time traffic. Power saving class of type II is recommended for real-time traffic. Power saving class of type III is recommended for manage and multicasting traffic. Most of research focus on there is single traffic in the MS, while it is high probability there are different kinds of traffic in MS. Thus it is necessary to consider multiple power saving classes coexist in the MS. In this thesis, we design a sleep planning mechanism using next event happening prediction way for power saving class of type I sleep interval planning suggestion. And we consider different power saving classes coexist problem simultaneously. To provide different sleep planning strategy for different power saving classes coexist in the MS to utilize. Via simulations, we show that the proposed scheme outperforms the standard mechanism in terms of packet delay and energy conservation. Even the standard mechanism works with the synchronization operations, our scheme still performs better than the combine mechanism.
