本计画的中心主题是探讨认知无线电网路透过整合式动态频谱存取来提升系统的吞吐量、延迟与公平性的方法与理论。该研究将开发新的方法，以：1）将频谱感测扩展到不仅仅是在某些频谱带/信道处存在和不存在主要频谱用户的活动，而且还扩展到它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）利用考虑可能影响分组的递送延迟的所有因素（包括频谱感测延迟、传输延迟、排队延迟）的非常全面的延迟模型执行延迟感知频谱管理，以及频谱协商和调度延迟4）考虑公平性和吞吐量之间的权衡，以公平的方式共享频谱5）提出延迟-感知公平路由协议的吞吐量优化，共同考虑吞吐量，延迟和公平性沿着与动态频谱管理。该项目的重点是动态频谱接入是高度国家利益，可以创造频谱使用政策和相关行业的电信和信息技术部门的重大影响。该项目还将鼓励和包括代表性不足的学生和少数民族学生参加这项活动，同时将教育和推广计划扩大到本科生和K-12学生。

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 approaches 3) 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 delay4) 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.
