Enabled by regulatory changes and technology advances, cognitive radio (CR) is emerging as the promising solution for utilizing the radio spectrum in an efficient way to satisfy the increasing demands for spectrum access, and provide ubiquitous communications in the future generation of wireless systems. CR offers new perspectives for spectrum sharing opportunities. However, this can only be achieved by implementing intelligent, flexible and dynamic spectrum-sharing control and management between the different involved parties, e.g., service/content providers and users. This trend poses significant challenges, which range from defining the fundamental performance limits of this radio technology to designing communication strategies and protocols that ensure efficient deployment and operation of future cognitive radio networks (CRNs). In this context, the main goal of this research program is to advance fundamental contributions to enable essential functionalities in future CRNs. Our focus is on developing communication strategies and networking protocols that make the best use of the available resources and deliver ubiquitous communications and quality of service guarantee. To that end, we propose solutions built upon an agile architecture that provides the CRN with the most useful control capabilities and adaptation, and demonstrating an awareness of the environment and an ability to automatically react to changes and requirements. Our research program couples research and educational development closely, and will integrate communication theory and networking in a unique and natural fashion. We will introduce a quantitative, systematic and fundamental approach to CR networked communications. Our research will be in a leading position for providing smart and reliable communication schemes for these emerging environments. As such, significant technical and industrial impacts are expected from this research program. The new technologies to be developed will not only result in high-technology transfer, but will also contribute to placing Canada at a cutting-edge in the development of new wireless technologies. The research program will also provide leading-edge training for graduate students.

在监管变化和技术进步的推动下，认知无线电 (CR) 正在成为一种有前途的解决方案，可以有效地利用无线电频谱来满足日益增长的频谱接入需求，并在下一代无线系统中提供无处不在的通信。 CR 为频谱共享机会提供了新的视角。然而，这只能通过在不同参与方（例如服务/内容提供商和用户）之间实施智能、灵活和动态的频谱共享控制和管理来实现。这一趋势带来了重大挑战，从定义这种无线电技术的基本性能限制到设计确保未来认知无线电网络（CRN）高效部署和运行的通信策略和协议。在此背景下，该研究计划的主要目标是推进基础性贡献，以实现未来 CRN 的基本功能。我们的重点是开发通信策略和网络协议，以充分利用可用资源并提供无处不在的通信和服务质量保证。为此，我们提出了基于敏捷架构的解决方案，为 CRN 提供最有用的控制功能和适应能力，并展示对环境的感知以及对变化和需求自动做出反应的能力。我们的研究项目将研究和教育发展紧密结合起来，并将以独特和自然的方式整合传播理论和网络。我们将介绍一种定量的、系统的、基本的 CR 网络通信方法。我们的研究将在为这些新兴环境提供智能、可靠的通信方案方面处于领先地位。因此，预计该研究计划将产生重大的技术和工业影响。即将开发的新技术不仅将带来高科技转让，还将有助于使加拿大处于新无线技术开发的前沿。该研究计划还将为研究生提供前沿培训。
