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

该项目的目标是建立一个跨越美国和欧洲多个地点的分布式实验基础设施，该基础设施在促进全球规模移动服务的实验研究方面具有独特的地位。该基础设施将包括在纽约和麦迪逊以及欧洲的CERTH和IBBT的不同地点的摄像头和触摸屏显示器，允许其用户通过第二层隧道进行基于无线的连接。该项目将使全球范围内的分布式移动服务研究成为可能。研究问题围绕着在全球不同位置放置计算的权衡，以及如何最好地复制这些计算，以在此类服务的性能延迟、带宽消耗和运营成本之间进行优化。PI正在考虑一种他们称之为分布式墙的应用程序，其中每个站点都有许多传感器和执行器，即运动检测摄像头和显示器。一项核心的局部计算任务是快速检测个人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全球不同地区调配服务器，以优化关键实验指标。拟议的成果包括更好地理解全球范围移动服务的分布式部署。该项目还具有重大的教育影响。项目督导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，该项目将把来自多个国家的学生聚集在一起，共同开展一个项目。这些学生将前往偏远地区，让他们接触到不同国家不同机构的研究，这些机构拥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.
