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

智能手机的大规模普及正在改变我们周围的世界。越来越多的用户在他们的口袋里携带着一个强大的计算、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、最普遍的分布式系统。今天，进行智能手机实验有两种主要方法：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下一代移动计算研究所需的能力、规模、现实性和密度。PhoneLab是一个公共测试平台，能够以前所未有的规模进行智能手机研究。PhoneLab为纽约州立大学布法罗分校的一大群参与者提供程序化访问。参与者使用他们的PhoneLab智能手机作为他们的主要设备，产生高地理密度和代表性的使用模式。PhoneLab允许研究人员分发应用程序或修改核心智能手机平台，促进广泛的实验。通过提供对相同参与者的重复访问，可以验证结果，可以比较竞争方法，并且可以利用现有数据进行新的实验。PhoneLab的能力将加速智能手机的研究，并导致无线网络、分布式和移动系统、移动传感、社交网络和众包的进步。PhoneLab还将在教学和学习中发挥重要作用，为大学和中学的科学项目提供新的作业。通过让学生接触智能手机的变革力量，PhoneLab将激发下一代计算机科学家。

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.
