This proposal is motivated by the observation that the battery drain of an app in a mobile device is user-centric, i.e., it depends on several factors that are associated with specific usage patterns. These factors include but are not limited to the mode in which the app is used, the network coverage that the user enjoys and whether or not certain features of the app are turned on/off. In this project, the objectives are to (i) develop a fundamental understanding of the factors that influence the energy consumption of smartphone apps and, (ii) based on the understanding obtained, design and implement a user-centric battery management system that is called BLT. The PIs plan to first undertake an extensive measurement study that will provide a comprehensive understanding of how and to what extent user-centric factors affect the energy consumption on a smartphone. Subsequently, they aim to tackle several challenges towards identifying the energy hungry apps on a user's smartphone; some of these challenges include the presence of several coexisting active apps at any given time. Finally, they will design and implement a set of solutions that allow a user to trade-off performance or content quality for energy savings. This project hinges on a strong experimental and prototyping effort, and the PIs will leverage the smartphone testbeds at UC Riverside and UC Davis towards undertaking the same.The project will have an immediate broader impact in empowering users with an ability to control their battery usage. It will also allow users and developers in understanding why activities and apps result in high battery drain. The project will also undertake efforts towards inspiring K-12 students in our respective regions, and helping teachers develop projects for science olympiads. The project will include the modification of wireless networking courses taught at UCD and UCR, and new educational efforts on establishing courses that include design and implementation on mobile devices.

该提议的动机是观察到移动终端中的应用的电池消耗是以用户为中心的，即，它取决于与特定使用模式相关联的若干因素。 这些因素包括但不限于应用程序的使用模式，用户享受的网络覆盖范围以及应用程序的某些功能是否打开/关闭。在这个项目中，目标是（i）对影响智能手机应用程序能耗的因素有一个基本的了解，（ii）基于所获得的理解，设计和实现一个以用户为中心的电池管理系统，称为BLT。 PI计划首先进行广泛的测量研究，以全面了解以用户为中心的因素如何以及在多大程度上影响智能手机的能耗。随后，他们的目标是解决识别用户智能手机上的耗能应用程序的几个挑战;其中一些挑战包括在任何给定时间存在多个共存的活动应用程序。 最后，他们将设计和实施一套解决方案，允许用户在性能或内容质量之间进行权衡，以节省能源。 该项目依赖于强大的实验和原型设计工作，PI将利用加州大学滨江分校和加州大学戴维斯分校的智能手机测试平台进行同样的工作。该项目将立即产生更广泛的影响，使用户能够控制他们的电池使用。 它还将允许用户和开发人员了解为什么活动和应用程序会导致高电池消耗。 该项目还将努力激励我们各自地区的K-12学生，并帮助教师开发科学奥林匹克项目。 该项目将包括修改UCD和UCR教授的无线网络课程，以及建立包括移动的设备设计和实施的课程的新教育努力。
