PHONELAB四年试验经验
Lessons from Four Years of PHONELAB Experimentation
摘要：
在过去的四年里，我们运营了一个名为PHONELAB的公共智能手机平台测试平台。PHONELAB由数百名参与者组成，他们在他们的主要智能手机上运行实验平台图像。该实验平台包括对平台组件（包括核心Android服务和Linux）的测试和实验更改。本文介绍了测试平台的设计，进行PHONELAB实验的过程中，和一些研究的测试平台支持。我们还提供了许多在此过程中学到的经验教训，几乎所有这些都是通过艰难的方式学到的-通过尝试和大量的错误。我们希望我们的经验将有助于那些考虑操作大型面向用户的测试平台的人，任何在智能手机上进行实验的人，以及许多移动系统研究人员。
英文摘要：
Over the last four years we have operated a public smartphone platform testbed called PHONELAB. PHONELAB consists of up to several-hundred participants who run an experimental platform image on their primary smartphone. The experimental platform consists of both instrumentation and experimental changes to platform components, including core Android services and Linux. This paper describes the design of the testbed, the process of conducting PHONELAB experiments, and some of the research the testbed has supported. We also offer many lessons learned along the way, almost all of which have been learned the hard way--through trial and a lot of error. We expect our experiences will help those contemplating operating large user-facing testbeds, anyone conducting experiments on smartphones, and many mobile systems researchers.
