Android平台的能源管理機制與實作

Abstract

隨著Android平台移動設備的迅速普及化，如何管理移動設備有限的電池能源，來延長Android平台移動設備的可使用時間，便成為了重要的課題。在本篇論文中，我們在ARM Coretex A8開發板上模擬Android平台移動裝置，使用了Android gingerbread 作業系統與Linux核心版本2.6.35，我們更在其中加入改良過能對應多種使用者情境的wake lock機制。透過實驗結果顯示，這些機制能有效的進一步控制Android平台移動裝置的能源消耗，來達到延長設備使用時間的效益。

With the fast popularization of Android platform mobile devices, how to manage the limited power of mobile devices to extend the utilizing time of Android platform mobile devices has become an important issue. In this paper, we choose an ARM Cortex A8 evaluation board to simulate the Android platform mobile devices. This evaluation board is equipped with the Android version “gingerbread” and Linux kernel version 2.6.35, we add the improved wake-lock mechanism to consider different user's situations. Results of the experiments reveal the mechanism can further control the power consumption of Android platform mobile devices to achieve the benefit of extending the utilizing time of mobile devices effectively.
