Collaborative Research: CRI: Large-Scale Open Sensor Network Testbed for Urban Monitoring

这个合作项目部署了一个用于城市监测的大规模开放式传感器网络测试平台（称为CitySense），旨在建立一个由城市电力供电的节点组成的大规模城市传感器测试平台，然后将其作为学术和工业团体的开放式设施进行运营，以试验新型分布式传感架构。模块化网络节点将连接到路灯上供电。这些节点包含足够的处理能力和内存，可以处理各种实验软件，加上无线电，可以通过跨剑桥的多跳网络将所有节点连接到其有线接入点。每个节点都带有闪存软件，以提供强大的传感器网络架构，包括可靠的ad hoc网络。CitySense将在一个特定的应用中进行测试：在密集的城市环境中监测空气污染传输。CitySense旨在推动传感器网络测试平台的发展，它包含一套基本的气象和空气质量传感器，可支持大规模传感器网络中的广泛研究项目。使许多研究实验与一个真实的大规模的原位无线传感器网络，整体研究的重点是：-高层次的编程模型的无线传感器网络，-资源共享之间的多个用户的试验台，-从地理上不同的传感器网络的数据收集，和城市规模的空气污染监测。更广泛的影响：通过提供一个永久的，可扩展的，公共的测试床，CitySense应该有重大影响的大规模无线传感器网络系统的发展。开放的城市范围的测试平台允许外部团体远程下载他们的软件映像到网络中的所有节点，或者当多个团体共享测试平台时下载到传感器条带中。监测密集城市环境中的空气污染传输，该应用程序构成了污染及其对城市人口影响的首批高分辨率研究之一。此外，CitySense将被用作教授分布式系统概念的工具。外联涉及传感器网络中的K-12课程开发。

This collaborative project, deploying a large-scale open sensor network testbed for urban monitoring (called CitySense), aims at building a large-scale, urban sensor testbed of nodes powered by city electricity and then operating it as an open facility for academic and industrial groups to experiment with novel distributed sensing architectures. The modular network nodes will be attached to streetlights for power. These nodes contain sufficient processing power and memory to handle a wide range of experimental software, plus radios to interconnect all the nodes by multi-hop networking across Cambridge to its wireline access points. Each node comes with software in flash to provide a robust sensor network architecture including reliable ad hoc networking. CitySense will be tested with a specific application: monitoring air pollution transport in a dense urban environment. Aiming at pushing the envelope for sensor network testbeds, CitySense contains a basic set of meteorological and air quality sensors supporting a broad range of research projects in large-scale sensor networks. Enabling many research experiments with a real large-scale in-situ WSN, the overall research focuses on:-High-level programming models for WSN,-Resource sharing among multiple users of the testbed,-Data collection from geographically diverse sensor nets, and-Urban-scale air pollution monitoring. Broader Impact: By providing a permanent, extensible, public testbed, CitySense should have significant impact on the development of large-scale wireless sensor network systems. The open city-wide testbed allows external groups to remotely download their software images into all the nodes in the network, or into a sensor swath when multiple groups share the testbed. Monitoring air pollution transport in a dense urban environment, the application constitutes one of the first high-resolution studies of pollution and its effect on the urban population. Moreover, CitySense will be used as a tool to teach distributed systems concepts. Outreach involves curriculum development for K-12 in sensor networks.
