CI-ADDO-NEW: PhoneLab: A Programmable Participatory Smartphone Testbed

智能手机的大规模部署正在改变我们周围的世界。越来越多的用户在口袋里携带着强大的计算、通信和传感平台，不断增长的全球智能手机网络已经构成了有史以来最强大和最普遍的分布式系统。如今，进行智能手机实验的主要方法有两种：通过应用程序市场分发实验，或者召集一组参与者进行一项研究。不幸的是，这两种方法都无法提供实现下一代移动计算研究所需的能力、规模、真实性和密度。PhoneLab是一个公共试验台，使智能手机研究达到前所未有的规模。PhoneLab为纽约州立大学布法罗分校的一大群参与者提供了编程访问权限。参与者使用他们的PhoneLab智能手机作为他们的主要设备，产生高地理密度和典型的使用模式。PhoneLab允许研究人员分发应用程序或修改核心智能手机平台，从而促进了广泛的实验。通过向相同的参与者提供重复访问，可以验证结果，可以比较相互竞争的方法，新的实验可以利用现有的数据。PhoneLab的能力将加快智能手机的研究，并在无线网络、分布式和移动系统、移动传感、社交网络和众包方面带来进步。PhoneLab还将在教和学方面发挥重要作用，使大学水平的新作业和中学科学项目成为可能。通过让学生接触到智能手机的变革性力量，PhoneLab将让下一代计算机科学家兴奋不已。

The mass deployment of smartphones is changing the world around us. Growing numbers of users carry a powerful computing, communication and sensing platform in their pocket, and the growing worldwide network of smartphones already constitutes the most powerful and pervasive distributed system ever built. Today there are two primary methods for performing smartphone experimentation: distributing experiments through an application marketplace, or assembling a group of participants for a single study. Unfortunately, both of these approaches fail to provide the power, scale, realism and density necessary to enable next-generation mobile computing research.PhoneLab is a public testbed enabling smartphone research at a scale not previously possible. PhoneLab provides programmatic access to a large group of participants at SUNY Buffalo. Participants use their PhoneLab smartphone as their primary device, generating high geographic density and representative usage patterns. PhoneLab allows researchers to distribute applications or modify the core smartphone platform, facilitating a broad range of experiments. By providing repeated access to the same participants, results can be validated, competing approaches can be compared, and new experiments can utilize existing data. PhoneLab's capabilities will accelerate smartphone research and lead to advances in wireless networking, distributed and mobile systems, mobile sensing, social networking, and crowdsourcing. PhoneLab will also play a vital role in teaching and learning, enabling both new assignments at the college level and secondary school science projects. By exposing students to the transformative power of smartphones, PhoneLab will excite the next generation of computer scientists.
