Existing spectrum-sharing paradigms have set clear boundaries between primary and secondary networks. There is very limited node-level cooperation between primary and secondary networks. This project develops a new and bold paradigm that explores policy-based network cooperation as a new dimension for spectrum sharing between primary and secondary networks. The benefits of this paradigm are numerous, as it allows integrating resources from two networks. To move this new paradigm from concept to reality, this project aims to (1) develop fundamental understanding of policy-based cooperation through mathematical models and optimization, (2) explore new achievable rate regions through the use of advanced physical layer technologies, and (3) develop distributed optimization algorithms that can offer performance approaching the theoretical limits. For prototype, the project implements the policy-based cooperation on a 48-node testbed.The project investigates a new paradigm and technologies that enable more flexible and efficient sharing of the radio spectrum. New mathematical models developed in this research will help gain fundamental understanding of the benefits of the new paradigm. The use of advanced physical layer technologies will further push the performance envelopes of achievable rate regions. New textbooks will be developed and used in classrooms at Virginia Tech and other universities. Special efforts to broadening participation by female and underrepresented students are planned through an on-going NSF REU site for cognitive radio communications and Virginia Tech's participation in Pacesetters, a program organized by the National Center for Women and Information Technology.

现有的频谱共享范例已在主要网络和辅助网络之间设置明确的界限。主要网络和次级网络之间的节点级合作非常有限。该项目开发了一个新的大胆范式，该范式探讨了基于策略的网络合作，作为主要网络和辅助网络之间频谱共享的新维度。该范式的好处很多，因为它允许整合两个网络的资源。 为了将这种新的范式从概念转变为现实，该项目的目的是（1）通过数学模型和优化对基于政策的合作进行基本理解，（2）通过使用先进的物理层技术探索新的可实现的速率区域，（3）开发分布式优化算法，这些算法可以提供接近理论极限的性能。对于原型，该项目在48节点的测试床上实现了基于政策的合作。该项目研究了一种新的范式和技术，使无线电频谱更加灵活，更有效地共享。 这项研究中开发的新数学模型将有助于获得对新范式的好处的基本理解。先进的物理层技术的使用将进一步推动可实现的速率区域的性能信封。 新教科书将在弗吉尼亚理工大学和其他大学的教室中开发和使用。计划通过正在进行的NSF REU网站进行认知无线电通信和Virginia Tech参与Paceseters的特殊努力，以扩大女性和代表性不足的学生的参与，这是由国家妇女和信息技术中心组织的计划。
