题目：认知无线网络（Cognitive Radio Networks）
Cognitive Radio (CR) technology has gained a lot of attention recently due to its capability of dynamically capturing the unoccupied spectrum. CRs are expected to be an important technology driver for wireless networks of the future. They will enable wireless devices to flexibly create many different kinds of communication links depending on the required performance and spectrum/interference constraints. In this talk, a framework of designing a secure and intelligent CR network will be introduced. The unique challenges and open problems in such networks will be identified and candidate solutions will be discussed.
