RR: Wireless Wind Tunnel: A Testbed for Experimental Evaluation of Wireless Networks

该项目旨在评估无线网络协议并开发物理环境的缩放技术，旨在部署用于干扰控制的消声室，形成一个被称为无线风洞的测试平台。该测试平台的用途主要集中在：在受控环境中评估无线协议（WP），开发适合基于仿真的WP评估的信道模型，以及评估扩展物理环境以促进现实无线实验的技术。无线风洞（WWT）解决了一些基于计算机评估的局限性，这些局限性是由于目前对无线网络的信道和系统模型的理解不足而造成的。这些都不是很好地理解和蛮力准确模拟无线环境目前太复杂。现有的硬件测试平台存在以下一种或两种缺点：由于在同一频率范围内工作的其他无线设备的干扰，实验往往不能重复，并且实验的参数（例如移动设备和环境中的散射体的移动模式）不是完全可控的。更广泛的影响：这项工作影响教育使命，包括课程作业、实验室、学生项目。测试平台将作为演示工具。新的教育机会将开放，包括提供更好的训练和动力的实验研究。设施将提供给更多的研究人员。在实际操作中，预计会对通信系统产生额外的影响。

This project, evaluating protocols for wireless networks and developing scaling techniques for physical environments, aims at deploying an anechoic chamber for interference control, forming a testbed, referred to as the Wireless Wind Tunnel. The uses of the testbed focus on: Evaluation of wireless protocols (WP) in controlled environments, Development of channel models suitable for simulation-based evaluation of WPs, and Evaluation of techniques for scaling the physical environment to facilitate realistic wireless experiments.The Wireless Wind Tunnel (WWT) addresses some of the limitations based on computer evaluations resulting from the present insufficient understanding of channel and system models for wireless networks. These are not well understood and brute force accurate simulation of the wireless environment are at present too complex. Existing hardware testbeds suffer from one or both of the following shortcomings: Experiments often cannot be repeated due to interference by other wireless devices operating in the same frequency range and The parameters of the experiment (such as the mobility patterns of the mobiles and scatterers in the environment) are not fully controllable.Broader Impact: This work impacts the education mission, including course work, laboratories, student projects. The testbed will serve as a demonstration tool. New educational opportunities will open involving experimental research providing better training and motivation. Facilities will be made available to a larger pool of researchers. Additional impact is expected on communications systems in practice.
