摘要:

智能手机在日常任务中的使用越来越多,这激发了许多关于能耗表征的研究,旨在提高智能手机设备的效率并增加用户使用时间。在这种情况下,研究能够表征用户使用模式的机制至关重要,因此智能手机的组件可以适应以更低的能耗促进最佳用户体验。本研究的目标是建立一个基于用户使用模式的能源消耗模型,旨在提供最准确的模型,供应用程序开发人员使用和自动优化。为了开发能耗模型,我们建立了一种方法来识别智能手机能耗中影响最大的组件,并识别每个有影响力的设备的状态。此外,我们建立了一种方法来证明使用不准确的硬件构建的模型的鲁棒性和评估所建立的模型的准确性的策略。在训练和测试每个策略以基于用户的使用对能耗进行建模并执行Nemenyi测试之后,我们证明了当智能手机的平均功率为1970.1mW时,可以获得158.57mW的平均绝对误差。一些研究表明,智能手机的主要工作负载是用户。基于这一事实,我们开发了一种自动模型构建方法,该方法能够分析用户的使用数据并构建智能模型,该模型可以根据用户的使用模式估计智能手机的能耗。通过自动模型构建方法,我们可以采取策略来最大限度地减少消耗电池的组件的使用。

英文摘要:

The increasing usage of smartphones in everyday tasks has been motivated many studies on energy consumption characterization aiming to improve smartphone devices' effectiveness and increase user usage time. In this scenario, it is essential to study mechanisms capable of characterizing user usage patterns, so smartphones' components can be adapted to promote the best user experience with lower energy consumption. The goal of this study is to build an energy consumption model based on user usage patterns aiming to provide the best accurate model to be used by application developers and automated optimization. To develop the energy consumption models, we established a method to identify the components with the most influence in the smartphone's energy consumption and identify the states of each influential device. Besides that, we established a method to prove the robustness of the models constructed using inaccurate hardware and a strategy to assess the accuracy of the model built. After training and testing each strategy to model the energy consumption based on the user's usage and perform the Nemenyi test, we demonstrated that it is possible to get a Mean Absolute Error of 158.57mW when the smartphone's average power is 1970.1mW. Some studies show that the leading smartphone's workload is the user. Based on this fact, we developed an automatic model building methodology that is capable of analyzing the user's usage data and build smart models that can estimate the smartphone's energy consumption based on the user's usage pattern. With the automatic model building methodology, we can adopt strategies to minimize the usage of components that drain the battery.
