认知无线电是一种很有前途的技术，可以显着缓解频谱紧缺问题，提高频谱利用率。该项目对开发社会和上下文感知频谱管理框架进行了全面的研究，旨在最大化具有不同设备和应用的认知无线电网络的频谱效率。这项研究的动机是，频谱的有效管理需要考虑用户和他们的应用程序相互交互的整个网络生态系统。在该框架中，针对所考虑的网络场景，提出了一种新的公平性准则。以改进的公平准则为约束，提出了一种社会和上下文感知的频谱分配方案，该方案有助于最大化频谱效率。此外，为了进一步提高频谱效率，还提出了一种公平的机会频谱共享机制。最后，利用一组用户的社会纽带的各个方面来减少频谱共享过程中的延迟。该项目的预期结果包括新的算法、设计和技术，使未来能够部署商业认知无线电网络和新的新兴应用。该项目的调查结果将通过期刊和会议出版物传播。开发的硬件和软件工具也将向整个研究界提供。该项目将研究和教育相结合，旨在培养本科生。它还延伸到当地的高中生。

Cognitive radio is a promising technology that can significantly alleviate spectrum scarcity and improve the spectral efficiency. This project conducts a comprehensive study on developing a social and context aware spectrum management framework that targets maximizing the spectral efficiency for cognitive radio networks with heterogeneous devices and applications. This research is motivated by the idea that the efficient management of spectrum requires the consideration of the entire network ecosystem where the users and their applications interact with each other. In the proposed framework, a novel fairness criterion is developed for the network scenarios under consideration. With the developed fairness criterion as a constraint, a social and context aware spectrum allocation scheme is developed, which contributes to the maximization of the spectral efficiency. In addition, a fair opportunistic spectrum sharing mechanism is proposed to further improve the spectral efficiency. Lastly, various aspects of social bonding in a group of users are exploited to reduce the delay occurred in the spectrum sharing process.The expected results of this project include novel algorithms, designs, and technologies to enable the future deployment of commercial cognitive radio networks and new emerging applications. The findings of this project will be disseminated through journal and conference publications. The developed hardware and software tools will be made available to the research community at large as well. The project integrates research and education with the intent of training undergraduate students. It also outreaches to high school students in the local area.
