CI-SUSTAIN: Collaborative Research: Sustaining Successful Smartphone Testbeds to Enable Diverse Mobile Experiments

今天，智能手机无处不在：连接、通知、引导、量化和娱乐我们。充满活力的智能手机软件市场让世界各地的开发者开发的数百万个有用的应用程序触手可及。但是，尽管任何人都可以开发和部署智能手机应用程序，但应用程序依赖于底层智能手机平台和操作系统提供的功能。智能手机平台软件负责节能和延长电池寿命，确定使用什么网络连接来平衡速度和成本，准确高效地确定设备？S的位置，以及其他关键任务。然而，智能手机平台受到智能手机供应商的严格控制，因此研究人员很难对其进行修改或改进。PhoneLab通过允许系统和网络研究人员修改安装在数百名用户上的智能手机平台来解决这一实验差距？主要的智能手机。该项目继续支持PhoneLab社区基础设施试验台再运行一年，同时追求更长期的可持续发展选项。PhoneLab由数百个布法罗大学附属机构组成，作为参与者。参与者携带的智能手机运行由PhoneLab管理员维护的定制Android平台映像。PhoneLab平台形象是与移动系统和网络社区合作维护的。在任何时候，它都包含用于生成数据集的工具，以及正在评估的新特性和新功能。一旦项目对人体受试者的安全性进行了审查，研究人员就可以下载他们的实验或之前的实验生成的数据集。在奖励期间，Sprint提供的折扣服务计划将激励PhoneLab参与者参加正在进行的实验。在此项目期间，PhoneLab将继续从外部可持续发展迁移到社区可持续发展，同时还将改进现有的Android仪器。

Today, smartphones are everywhere: connecting, informing, guiding, quantifying, and entertaining us. Vibrant smartphone software marketplaces put million of useful apps created by developers around the world at our fingertips. But while anyone can develop and deploy a smartphone app, apps rely on functionality provided by the underlying smartphone platform and operating system. The smartphone platform software is responsible conserving energy and prolonging battery lifetime, determining what network connection to use to balance speed and cost, accurately and efficiently determining the device?s location, and other critical tasks. Yet, the smartphone platform is closely controlled by smartphone vendors and so very difficult for researchers to modify or improve. PhoneLab addresses this experimental gap by allowing systems and networking researchers to modify the smartphone platform installed on several hundred users? primary smartphones. This project provides continued support for the PhoneLab community infrastructure testbed to operate for another year, while it pursues longer-term sustainability options.PhoneLab consists of several hundred University at Buffalo affiliates who act as participants. Participants carry smartphones running a custom Android platform image maintained by PhoneLab administrators. The PhoneLab platform image is maintained in collaboration with the mobile systems and networking community. At any point it contains a mixture of instrumentation to generate datasets as well as novel features and new capabilities that are being evaluated. Once projects are reviewed for human subjects safety, researchers can download datasets generated by their experiments or by previous experiments. During the period of the award, PhoneLab participants will be incentivized to join ongoing experiments by a discounted service plan provided by Sprint. During this project period, PhoneLab will be continuing to migrate from external to community sustainability while also improving the existing Android instrumentation.
