II-EN: A Metro-Scale Vehicular Wireless Testbed with Spectrum Awareness and Spectrum Agility

该项目建立了一个独特的大城市规模的车载无线测试平台，称为MadBed，具有广域无线连接的能力，专门设计的节点安装在麦迪逊地区的城市公交车上。该测试平台还被用来为这些城市公交车的乘客提供互联网服务。此外，测试台还向总线网络提供各种车辆通信服务，例如，城市公交车的跟踪，以及一些专门的执法能力。该基础设施使大量的专业无线和移动的网络研究项目在威斯康星大学麦迪逊分校校园。一些例子包括探索新的无线网络管理技术的广域无线网络，探索在设计新的合作MAC协议，探索在广域频谱感知和利用，并在车辆延迟容忍network.As其教育组件的一部分，MadBed是允许一个更大的动手经验，学生在课堂上的设计和性能的广域无线环境。在其推广部分，MadBed的PI与一个名为威斯康星州教育传播委员会的当地政府组织合作，提供某些教育内容的全市广播。PI还为某些当地高中生组织年度访问日，并通过MadBed的各个方面，让他们了解计算机职业的一些有趣方面。最后，MadBed还与许多地方，国家和国际工业合作伙伴建立了巨大的协同效应，例如，思科斯普林特疯狂城市宽带

This project builds a unique metro-scale, vehicular wireless testbed, called MadBed, with capabilities for wide-area wireless connectivity, with specially designed nodes mounted on Madison area city buses. The testbed is also being leveraged to provide Internet services to the passengers of these city buses. Further the testbed is also providing various vehicular communication servicesto the bus network, e.g., tracking of city buses, and some specialized law enforcement capabilities. The infrastructure is enabling a large number of specialized wireless and mobile networking research projects in the UW-Madison campus. A few examples include exploration of new wireless network management techniques for wide-area wireless networks, exploration in design of new cooperative MAC protocols, exploration in wide-area spectrum sensing and their utilization, and in vehicular delay tolerant networking.As part of its educational component, MadBed is allowing a greater hands-on experience to students in the classroom on design and performance of wide-area wireless environments. In its outreach component, the PIs of MadBed arepartnering with a local governmental organization called Educational Communications Board of Wisconsin to to provide city-wide broadcasts of certain educational content. The PIs are also organizing annual visit days for certainlocal area high schoolers, and exposing them to some interesting aspects of careers in computing, through various aspects of MadBed. Finally, MadBed has also built great synergies with a number of local, national, and internationalindustrial partners, e.g., Cisco, Sprint, MadCity Broadband.
