dc.description.abstract | 為了保持與傳統桌上型電腦一樣的功能,一種典型的應用程式類
型-常駐程式透過頻繁地喚醒待機中的行動裝置來保持應用程式的正常 運行與硬體元件的使用,即使使用者根本沒有使用此應用程式。這使 得保持在待機狀態的行動裝置時時保持在喚醒狀態,巨量, 快速地消耗 有限的電池,這個問題隨著使用者安裝的應用程式越來越多樣而越來 越嚴重。在這篇論文,我們發現目前行動裝置對於應用程式的事件規 劃並沒有為待機狀態的行動裝置做最佳化,因此,我們探以事件相似 度的觀點來同時表達兩個相反的目標-使用者體驗與節能, 透過合併相 似度高的事件並同時達成這兩個目標。越高的硬體使用相似度,代表 合併此事件帶來越多的節能;越高的時間相似度,代表合併此事件損 失越少的使用者體驗。除此之外,我們將此事件規劃的設計實作在市 售的智慧型手機上並結合市面上的應用程式驗證結果,實驗的結果顯 示若考量事件相似度的設計平均可以減少25% 應用程式事件的耗電, 最高可達32% 應用程式事件的耗電而不喪失使用者感受的到的事件的 使用者體驗。 | zh_TW |
dc.description.abstract | Resident applications are a typical type of mobile applications. In order
to maintain the same functionality as traditional desktop, the resident applications frequently awake the mobile device for processing and accessing of hardware components when the mobile devices are in sleep mode even if user doesn’t use the application. The problem gets worse with the increasing of installed mobile applications. In this paper, we show that existing event scheduler are not optimized for operation in connected standby mode and we exploit the concept of event similarity, which expresses two opposite goals, user experience and energy efficiency, simultaneously. With higher hardware similarity, the scheduler gains more energy reduction; with higher time similarity, the scheduler lose less impact of user experience. Furthermore, we integrate our design into the Android operating system and evaluate it with real-world mobile applications. The experimental results shows that the novel event scheduler reduces the average energy consumption by 25% and up to 32% with little impact on user experience. | en |
