CI-ADDO-EN: A Community Testbed for Controlled and Repeatable Wireless Experiments

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该项目部署了两个社区无线网络测试设施，使用实时信号传播仿真来实现连接无线设备的n × n干扰信道。由于信号的传播是在软件中控制的，实验很容易控制，并且完全可重复。这允许在一个平台上对研究结果进行全面的测试和评估，对无线解决方案进行公平的并排比较，并模拟非常多样化的无线环境（例如住宅，办公室，网状，车辆等）。测试平台在2.4 GHz ISM频段运行，并正在增加对5GHz频段和MIMO设备的支持。默认情况下，端点由WiFi设备和USRP软件无线电组成，但也可以支持其他设备。一组模拟特定无线环境（网格和车辆）的“世界模型”正在添加。这使得测试平台更容易使用，并简化了实验共享和结果比较。为了支持和鼓励这种共享，维护了一个共享实验的存储库。无线仿真试验台使研究人员能够进行可重复的、完全可控的无线网络实验，大大提高了研究评估的质量。通过分享实验，研究人员能够在一个现实的平台上更彻底地评估和比较他们的研究，否则这是不可能的。仿真器还通过实现令人兴奋的动手作业和项目来改善无线网络的教育。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This project is deploying two community wireless network test facilities that use real-time signal propagation emulation to implement the N-by-N interfering channels connecting the wireless devices. Since signal propagation is controlled in software, experiments are easy to control and are fully repeatable. This allows thorough testing and evaluation of research results, fair, side-by-side comparison of wireless solutions, and the emulation of very diverse wireless environments (e.g. residential, office, mesh, vehicular, etc.) on a single platform. The testbeds operate in the 2.4 GHz ISM band and support for the 5GHz band and for MIMO devices is being added. Endpoints consist of WiFi devices and USRP software radios by default, although other devices can be supported. A set of 'world models' that model specific wireless environments (mesh and vehicular) is being added. This makes the testbed easier to use, and simplifies sharing of experiments and comparing of results. To support and encourage such sharing, a repository for shared experiments is maintained. The wireless emulator testbed allows researchers to run repeatable and fully controlled wireless networking experiments, which significantly improves the quality of the research evaluation. By sharing experiments, researchers are able to more thoroughly evaluate and compare their research on a realistic platform, which otherwise would not have been possible. The emulator also improves education in wireless networking by enabling exciting hands-on assignments and projects.
