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

这一合作项目部署了一个用于城市监测的大规模开放传感器网络试验台(称为CitySense)，旨在建立一个由城市电力供电的大规模城市传感器试验台，然后将其作为开放设施，供学术和工业团体试验新型分布式传感体系结构。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来处理广泛的实验软件，外加无线电，通过剑桥的多跳网络将所有节点互连到其有线接入点。每个节点都配有闪存中的软件，以提供强大的传感器网络体系结构，包括可靠的自组织网络。CitySense将通过一个具体的应用进行测试：监测密集城市环境中的空气污染运输。CitySense旨在推动传感器网络试验台的发展，它包含一套基本的气象和空气质量传感器，支持大规模传感器网络中的广泛研究项目。通过使用真正大规模的现场无线传感器网络进行许多研究实验，整体研究集中在：-WSN的高级编程模型，-试验床多用户之间的资源共享，-从地理上不同的传感器网络收集数据，以及-城市规模的空气污染监测。更广泛的影响：通过提供永久的、可扩展的公共试验床，CitySense应该会对大规模无线传感器网络系统的开发产生重大影响。开放的全市测试床允许外部组将其软件映像远程下载到网络中的所有节点，或者当多个组共享测试床时下载到传感器条带中。监测密集城市环境中的空气污染交通，这一应用构成了关于污染及其对城市人口影响的第一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。外展涉及传感器网络中K-12课程的开发。

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.
