该提案解决了与使用机会/认知频谱接入的无线个域网的设计、开发、性能分析和优化相关的研究问题，该无线个域网在下文中将被称为认知个域网或CPAN。将特别注意频谱感知，自适应调度，性能评估和优化的问题。认知无线电技术可以提高许多个域网应用中的频谱利用率，从而缓解阻碍无线通信进一步发展的频谱机会短缺问题。我们建议增加认知技术与跳频扩频技术，它提供了灵活性，可扩展性，生存能力，抗干扰和干扰，即使使用廉价的电池供电的设备。我们的研究将有助于通过更好的家庭网络，增加覆盖范围和无线传感器网络的服务质量，提高生活质量，并为紧急情况下的ad hoc网络提供有效和畅通的通信渠道。通过这种方式，这项研究将有助于提高生产力，增加盈利能力，并进一步增长加拿大经济。

This proposal addresses the research issues related to the design, development, performance analysis and optimization of wireless personal area networks that use opportunistic/cognitive spectrum access, which will hereafter be referred to as Cognitive Personal Area Networks, or CPANs. Particular attention will be given to issues of spectrum sensing, adaptive scheduling, and performance evaluation and optimization. Cognitive radio technology can improve spectral utilization in many personal area network applications, and thus alleviate the shortage of spectrum opportunities that impedes further development of wireless communications. We propose to augment cognitive technology with frequency hopping spread spectrum techniques, which provide flexibility, scalability, survivability, and resistance to interference and jamming, even when using inexpensive devices operating on battery power. Our research will contribute to improved quality of life through better home networks, increased coverage, and quality of service of wireless sensor networks, and provide efficient and unimpeded communication channels for ad hoc networks for emergency situations. In this manner, this research will contribute to improved productivity, increased profitability, and further growth of the Canadian economy.
