项目摘要

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动态频谱接入来增强认知无线电网络的吞吐量、延迟和公平性的方法和理论。该研究将开发新方法来：1）将频谱感知扩展到某些频段/信道上主要频谱用户活动的存在和不存在，以及他们的位置和发射功率2）预测主要频谱用户的活动及其使用博弈论和统计学习方法进行间隔3) 使用非常全面的延迟模型执行延迟感知频谱管理，考虑可能影响数据包传输延迟的所有因素，包括频谱感知延迟、传输延迟、排队延迟和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) 提出一种用于吞吐量优化的延迟感知公平路由协议，该协议结合考虑吞吐量、延迟和公平性以及动态频谱管理。该项目的重点是动态频谱访问具有高度的国家利益，可以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。该项目还将鼓励并让代表性不足的学生和少数族裔学生参与到这项活动中，同时将教育和推广计划扩展到本科生和 K-12 学生。
