WN: Real-Time Spectrum Auctioning Through Distributed Coordination

无线网络的激增极大地改变了我们的生活和工作方式。然而，由于目前的静态频谱分配，频谱短缺问题阻碍了无线创新和部署。虽然大多数频段已分配给现有的无线网络和技术，但它们严重未得到充分利用。这项研究将寻求使用动态频谱接入来提高频谱利用率。在这个新系统中，未来无线网络的组件不再具有静态分配的频谱。取而代之的是，他们要求按需频谱与他们的时变需求相匹配，并为他们使用的内容付费。为了充分挖掘动态频谱接入的潜力，本研究将致力于开发一种高效的频谱拍卖系统，将频谱定期拍卖给无线节点，并动态分配频谱以最大限度地减少干扰。该项目摆脱了传统的集中式解决方案，专注于分布式拍卖系统，以管理大范围地理区域内的大量频谱请求。该项目的成功将促进人们对动态频谱接入系统的理解，并对认知无线电和未来无线网络的发展产生影响。该项目的教育影响包括将研究与本科生和研究生的跨学科培训计划相结合。

Proliferation of wireless networks has dramatically changed the way we live and work. However, wireless innovation and deployment has been blocked by the spectrum shortage problem as a result of today's static spectrum assignment. While most spectrum bands have been allocated to existing wireless networks and technologies, they are severely under-utilized. This research will seek to improve spectrum utilization using dynamic spectrum access. In this new system, components of future wireless networks no longer have statically assigned spectrum. Instead, they request spectrum on-demand matching their time-varying demand and pay for what they use. To exploit the full potential of dynamic spectrum access, this research will focus on developing an efficient spectrum auction system which auctions spectrum periodically to wireless nodes and dynamically assign spectrum to minimize interference. Moving away from traditional centralized solutions, this project focuses on distributed auction system to manage large volume of spectrum requests across large geographic areas. The success of this project will advance understanding in dynamic spectrum access systems, and impact development of cognitive radios and future wireless networks. The educational impacts of the project include integration of research with interdisciplinary training programs at both undergraduate and graduate levels.
