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。这促使对频谱分配和管理政策进行重新评估。政策的变化将鼓励使用新的、更有效的动态频谱共享机制。本项目正在研究此类机构的设计和性能。目前正在考虑两种频谱管理策略方案。在独占模式下，频谱由所有者或被许可人独占管理，被许可人可以将频谱出租给其他人。在公共模式中，只要遵守公认的协议或标准（如未经许可的频段），任何人都可以使用频谱。该项目正在开发机制，以促进每种情况下的频谱共享，并试图描述各种机制实现的性能（例如，总效用）如何取决于对信息交换、计算和激励的约束。为了实现这一目标，无线通信和网络的建模和性能评估技术正在与基于经济学的技术（如博弈论和机制设计）相结合。预计这项工作将为不同频谱共享机制的行为以及与不同方法相关的权衡提供基本的见解。

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.
