摘　　要：认知无线电网络具有动态、灵活、智能地使用频谱资源,提高频谱利用率的特点,其网络结构和协议体系的设计是实现上述网络功能的关键。现有基于认知无线电技术的网络架构主要有美国的CORVUS系统,基于IEEE 802.22的无线局域网(WRAN)和支持多信道多接口的无线Mesh网络;协议体系有CORVUS协议体系,军用的XG系统协议及WRAN协议等。Cognitive radio networks have the abilities of utilizing spectrum dynamically, agilely and intelligently, and improving the efficiency of spectrum usage. Consequently, both the protocol and architectural designs for cognitive radio networks is very crucial. The network architectures in existing systems included contents are CORVUS system introduced in America, Wireless Regional Area Network （WRAN） based on IEEE 802.22 as well as the wireless Mesh network supporting multi-channel and multi-interface; related network protocols are of CORVUS system, the XG system for military applications, and WRAN.
