NeTS: Small: Collaborative Research: Transmission Re-Ordering in Wireless Networks: Protocols and Practice

该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)提供资金的。互联网的边缘继续在无线媒体上迅速传播。为了应对不断增长的需求，必须最大限度地利用无线网络中的每一个可用机会，特别是在物理层和更高层的边界。一种这样的机会是即使在存在干扰帧(即消息中消息(MIM))的情况下也成功捕获帧的能力。对于MIM，如果以特定顺序激活两个并发传输，则可能会成功，但反之亦然。为了利用MIM，本项目的目标是：i)通过理论分析了解MIM的内在潜力；ii)利用这种理解来设计高效的高层协议；iii)开发一个原型试验台来验证/评估MIM感知协议。该项目为更广泛的社区提供了明显的好处，因为它试图通过充分利用有限的频谱资源来满足无线网络上日益增长的带宽需求应用程序。此外，该项目还有助于：i)发展和加强南卡罗来纳大学和杜克大学的无线网络实验室和课程；ii)参与和指导本科生进行无线网络研究；iii)在Duke SmartHome中部署实验性无线技术。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The edge of the Internet continues to spread rapidly over the wireless medium. To cope with the escalating demand, every available opportunity in wireless networking will has to be maximally exploited, particularly at the border of physical and higher layers. One such opportunity is the capability of successfully capturing a frame even in the presence of an interfering frame, i.e., message-in-message (MIM). With MIM, two concurrent transmissions may be successful if they are activated in a specific order, but not the reverse. Towards harnessing MIM, this project aims to: i) Understand the intrinsic potential of MIM through theoretical analysis; ii) Draw on this understanding to design efficient higher layer protocols; iii) Develop a prototype testbed to validate/evaluate the MIM-aware protocols. This project offers obvious benefits to the broader community as it attempts to satiate the growing demand for bandwidth hungry applications over wireless networks by extracting the most from the scant spectral resources. Additionally, this project facilitates: i) Development and strengthening of the laboratory and curriculum for wireless networking at University of South Carolina and Duke University; ii) Involvement and mentoring of undergraduate students in wireless networking research; iii) Deployment of experimental wireless technologies within The Duke SmartHome.
