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》(Public Law 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乘N干扰信道。由于信号传播是由软件控制的，所以实验很容易控制，而且完全可以重复。这允许对研究结果进行彻底的测试和评估，公平地并排比较无线解决方案，以及模拟非常多样化的无线环境(例如住宅、办公室、网状网、车辆等)。在单一平台上。试验台在2.4 GHz ISM频段运行，并增加了对5 GHz频段和MIMO设备的支持。默认情况下，终端由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(网状和车载)的“世界模型”正在被添加。这使得试验台更易于使用，并简化了实验共享和结果比较。为了支持和鼓励这种共享，维护了共享实验的存储库。无线仿真器试验台允许研究人员进行可重复和完全受控的无线网络实验，显著提高了研究评估的质量。通过共享实验，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。该模拟器还通过支持令人兴奋的动手作业和项目来改进无线网络方面的教育。

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.
