基於傳輸減量之Android 平台電力節約機制

近幾年來數位手持裝置的快速發展以及無線寬頻技術的普及，使我們漸漸於習慣利用手持裝置來瀏覽網頁甚至透過無線傳輸使用MSN與朋友交談、收看線上節目、上網查詢資料或觀看YouTube的熱門影片等，這都是手持裝置顯著的進步所帶來的生活上便利。這無疑地說明手持裝置已經不再只是執行單一功能而已，如：收發信件或是語音通訊，而是將手持裝置朝向通訊、多媒體及娛樂等多功能的整合，使其成為一個行動多媒體娛樂裝置。但是以上這些功能，都有賴手持裝置上的電力維持，以及無線網路距離遠近所影響的傳輸頻寬，甚至是手持裝置上的記憶空間和CPU的計算能力。對於未來講求快速、便利、效率來看，這幾點因素都將會嚴重的影響手持裝置使用上的效率。本篇論文提出一個建構於Android平台的Agent機制以達到減少電力消耗、有效率使用頻寬，及資料減量方法以增加手持裝置的記憶空間使用效率，並考慮多應用程式時需求處理，使得手持裝置的使用不只便利且更持久。其主要概念是增加離線時間，減少連線次數；並在無可避免或必要建立連線時，充分使用剩餘頻寬，儘量減少網路閒置時間。

In recent years, handheld devices was developed rapidly and wireless broadband technology was popular. So that we were gradually in the habit of using handheld devices to browse the Web or even through wireless transmission using the MSN to chat with friends; we can watch online TV, search for information or watch the most popular YouTube videos, etc. The handheld devices are no longer just have a single function of voice communications or e-mail only. Instead, the handheld device was integrated the communication, multimedia, and amusement such as multi-functional integration making it a mobile multimedia amusement device. However, These functions depended upon handheld devices' power, as well as wireless transmission distance. And even handheld devices' memory space and CPU computing power. In the future, they will be emphases for the the speed, the convenience, and the efficiency. These factors will seriously affect the efficiency of the use of handheld devices. This paper proposed a building on the Android platform Agent mechanism to achieve the reduction in power's consumption, efficiently use the bandwidth, and the data reduction's method to increase the efficient use of memory space in handheld devices. And this paper will consider the needs of multi-application program processing, making the use of handheld devices is not only convenient and more durable. The main idea is to increase the off-line time, reduce the number of connections; when it is unavoidable or necessary to establish connection, we fully use the remaining bandwidth to minimize the network idle time.
