RI: An Infrastructure for Wide Area Pervasive Computing

该项目旨在创建普适计算设施的试点，覆盖建筑物的所有区域，包括办公室、演讲室、走廊和公共区域。试点将包括一个由建筑的很大一部分组成的异质空间。在这一区域，将有一个传感器网络，能够跟踪数百个移动客户端在大楼内自由移动时的精确度不到10英尺。研究影响：拟议的设施将用于推进从低水平系统建设到以人为本的应用程序等多个层面的研究。该设施将通过三个主要途径推进研究。首先，它将被用来理解密歇根大学开发的从纳米传感器到认知矫形术的新技术部署中的规模和异质性问题。其次，通过始终如一地使用这一设施收集的流动性痕迹将导致为移动系统/算法设计人员创建新的基准，以及实现卓越的建筑设计。第三，鉴于该系统需要跟踪许多建筑物的居住者，将有机会研究有趣的隐私问题和个人行使选择的方式。更广泛的影响：在密歇根大学，有许多正在进行和计划中的利用传感器技术和/或移动环境的研究工作。获得大型普及计算设施将是大规模测试这些技术并将其推向商业化的下一个阶段的关键。更重要的是，普适计算设施将与许多同事和学生一起部署在项目团队每天工作的大楼中。这带来了一种独特的“活生生的实验室”体验，通过它可以欣赏普适计算设施的技术和社会影响。

This project is to create the pilot for a pervasive computing facility through all areas of a building, including offices, lecture rooms, hallways, and common areas. The pilot will include a heterogeneous space comprising a significant fraction of a building. In this area, there will be a sensor network, capable of tracking hundreds of mobile clients to a granularity of less than 10 feet as they move freely through the building. Research Impact:The proposed facility will be used to advance research at a number of levels, from low-level system building to human-oriented applications. There are three main avenues through which this facility will advance research. First, it will be used to understand issues of scale and heterogeneity in the deployment of novel technologies that have been developed at the University of Michigan, ranging from nano-sensors to cognitive orthotics. Second, the mobility traces collected from the consistent use of this facility will lead both to the creation of new benchmarks for mobile system/algorithm designers as well as to superior building design. Third, given that the system requires the tracking of many building occupants, there will be an opportunity to study interesting issues of privacy and the manner in which individuals exercise choice. Broader Impact:At the University of Michigan, there are a number of on-going and planned research efforts that leverage sensor technology and/or mobile environments. Access to a large pervasive computing facility will be crucial to testing these technologies at scale and taking them to the next stage towards commercialization. More important, the pervasive computing facility will be deployed in the building in which the project team works everyday, along with many colleagues and students. This gives rise to a unique "living laboratory" experience through which to appreciate both the technological and social effects of the pervasive computing facility.
