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.
