NeTS-ProWiN: Smart Markets for Smart Radios

软件定义无线电的最新进展可能使无线应用能够定位和利用未充分利用的无线电频谱。这促使人们重新评估频谱分配和管理政策。政策的变化将鼓励使用新的和更有效的动态频谱共享机制。该项目正在研究这种机制的设计和性能。正在考虑两种频谱管理政策方案。在独占使用模式中，一段频谱由所有者或被许可人独占管理，他们可以将频谱出租给其他人。在公共模型中，频谱可以被任何人使用，只要他们遵守公认的协议或标准（如在未授权频段中）。该项目正在开发机制，以促进这些场景中的每一个的频谱共享，并试图表征性能（例如，总效用）取决于对信息交换、计算和激励的约束。为了实现这一点，无线通信和网络的建模和性能评估技术正在与基于经济的技术相结合，如博弈论和机制设计。预计这项工作将提供基本的洞察不同的频谱共享机制的行为沿着与不同的方法相关联的权衡。

Recent advances in software-defined radios can potentially enable wireless applications to locate and exploit underutilized radio spectrum. This has motivated a re-evaluation of policies for spectrum allocation and management. Changes in policy will encourage the use of new and more efficient mechanisms for dynamic spectrum sharing. This project is studying the design and performance of such mechanisms. Two policy scenarios for spectrum management are being considered. In the exclusive use model, a piece of spectrum is managed exclusively by the owner or licensee, who can lease the spectrum to others. In the commons model the spectrum can be used by anyone provided that they comply with an accepted protocol or standard (as in unlicensed bands). This project is developing mechanisms to facilitate spectrum sharing for each of these scenarios, and attempting to characterize how the performance (e.g., total utility) achieved by various mechanisms depends on constraints on information exchange, computation, and incentives. To accomplish this, modeling and performance evaluation techniques for wireless communications and networking are being combined with economic-based techniques, such as game theory and mechanism design. It is expected that this work will provide basic insight into the behavior of different spectrum sharing mechanisms along with the trade-offs associated with different approaches.
