摘要
认知无线电(Cognitive Radio)和认知网络(Cognitive Network)的提出和快速发展源于日益增长的网络可靠性、可用性和适应性要求。本文从当前网络面临的问题出发,首先介绍了认知无线电的提出背景和技术特点,并说明了认知网络的概念和内涵。然后,归纳了当前有关认知网络研究的相关研究工作。在此基础上,给出了一种通用的认知网络体系结构并对其资源管理方式进行了阐述。最后,总结了全文并展望了今后工作。
Cognitive Radio (CR) and Cognitive Network (CN) are proposed to meet requirements of increasing network dependability, availability and adaptability. Aiming current network puzzles, background and technical traits of CR are introduced firstly and concepts of CN are explained. Then, relevant research works of CN are summed up. Based on above expatiation, general architecture of CN is given and its resource management mode is elaborated. Finally, conclusion is drawn and future works are prospected.
