The central theme of this project is to investigate methodologies and theories to enhance throughput, delay, and fairness of cognitive radio networks via integrated dynamic spectrum access. The research will develop new methods to:1) Extend spectrum sensing beyond just the presence and absence of the primary spectrum users' activities at certain spectrum bands/channels, but also their locations and transmit powers 2) Predict the primary spectrum user's activity and its interval using game theoretic and statistical learning approaches3) Perform delay-aware spectrum management with a very comprehensive delay model considering all the factors that may affect the delivery latency of a packet, including the spectrum sensing delay, the transmission delay, the queuing delay, and the spectrum negotiation and scheduling delay 4) Share spectrum in a fair manner considering the tradeoff between fairness and throughput5) Propose a delay-aware fair routing protocol for throughput optimization which jointly considers throughput, delay, and fairness along with dynamic spectrum management.The project's focus on dynamic spectrum access is of high national interest and can create significant impact on spectral usage policies and related industries in the telecommunication and information technology sectors. The project will also encourage and include under-represented and minority students to be part of this activity, while extending education and outreach plans to undergraduates and K-12 students.

该项目的中心主题是研究通过集成的动态频谱接入来提高认知无线电网络的吞吐量、时延和公平性的方法和理论。该研究将开发新的方法来：1)将频谱侦听扩展到不仅仅是主要频谱用户在特定频带/信道上的活动的存在和不存在，而且还包括他们的位置和发射功率2)使用博弈论和统计学习方法来预测主要频谱用户的活动及其间隔3)使用非常全面的延迟模型执行延迟感知频谱管理，考虑可能影响分组传递延迟的所有因素，包括频谱感知延迟、传输延迟、排队延迟、而频谱协商和调度延迟4)在兼顾公平性和吞吐量的前提下，公平地共享频谱。5)提出了一种综合考虑吞吐量、时延和公平性以及动态频谱管理的时延感知公平路由协议。该项目对动态频谱接入的关注事关国家利益，对电信和信息技术领域的频谱使用政策和相关行业产生重大影响。该项目还将鼓励和包括代表不足的学生和少数族裔学生参加这项活动，同时将教育和外联计划扩大到本科生和K-12学生。
