EAGER: Collaborative: A Multi-Party Distributed Wall through Dispersed Sensing and Computation

该项目的目标是建立一个分布式实验基础设施，跨越多个地点在美国和欧洲，是独特的定位，以促进全球规模的移动的服务的实验研究。该基础设施将包括摄像头和触摸屏显示器在不同的地点在纽约和麦迪逊以及在欧洲的CERTH和IBBT，允许无线为基础的连接，其用户通过第2层隧道。该项目将使分布式移动的服务的研究在全球范围内。研究问题围绕着在地球仪的不同位置放置计算的权衡，以及如何最好地复制它们，以优化性能延迟，带宽消耗和运营成本之间的这种服务。PI正在考虑一种他们称之为分布式墙的应用，其中每个站点都有一些传感器和执行器，即运动检测摄像头和显示器。一个核心的本地计算任务是快速检测个体并将摄像机聚焦到他们身上。随着站点数量的增长，应用程序开发人员面临的一个关键挑战是确定如何以及何时在地球仪的不同部分配置服务器，以优化关键的实验指标。建议的成果包括更好地理解全球规模的移动的服务的分布式部署。该项目也具有重大的教育影响。项目研究员将通过各自大学的各种网络和无线通信课程，将项目中的知识融入课堂。此外，该项目将把来自几个国家的学生聚集在一起，共同完成一个项目。学生将前往偏远地区，让他们接触到不同国家的不同机构的研究，这些机构具有不同的研究文化和解决网络研究的方法。

The goal of this project is to build a distributed experimentation infrastructure spanning multiple sites in the US and Europe that is uniquely positioned to facilitate experimental research on global scale mobile services. The infrastructure would consist of cameras and touch-screen displays at different locations in New York and Madison as well as in CERTH and IBBT In Europe, allowing wireless based connectivity for its users through a layer 2 tunnel.This project will enable research in distributed mobile services at a global scale. The research questions revolve around tradeoffs in placing computation across diverse locations around the globe and how they should be best replicated to optimize between performance latencies, bandwidth consumed and operational costs of such a service. The PIs are considering an application that they call a distributed wall where each site has a number or sensors and actuators, i.e. motion-detecting cameras and displays. A core local computational task is to quickly detect individuals and focus the cameras on them. As the number of sites grows, a key challenge for the application developers is to determine how and when to provision servers in different parts of the globe to optimize on the key experimental metrics. The proposed outcomes include better understanding of distributed deployment of global scale mobile services.The project also has significant educational impact. The PIs will incorporate learnings from the project into the classroom through various networking and wireless communication courses at the respective universities. In addition, this project will bring students together from several countries to work together on a single project. The students will travel to the remote locations to give them exposure to research in different institutions across different countries with different research cultures and approaches to addressing networking research.
