摘要 在对近期认知无线电网络路由研究成果进行研究的基础上,从邻居节点发现、"耳聋"、邻居节点消失、路由发现和跨层设计等5个方面,对认知无线电网络路由研究面临的重要挑战进行了分析;从研究方法的角度,对路由研究中对公共控制信道的依赖、路径延时,以及需要考虑的技术指标进行了讨论.最后,从介质、信道、节点和网络等4个方面,对路由研究场景设计进行了归纳总结;并从路由优化方案和路由拓扑算法协议两个方面,对主要研究成果进行了分析和讨论. Based on the analyses of the recent routing research productions of the cognitive radio networks(CRN),this paper identifies five critical challenges on the routing research of CRN:neighbor discovery,deafness problem,neighbor disappearance,routing problem and cross-layer design,then some topics about common control channel,path delay and the technical metrics are discussed from the view of research method,which must be considered on the routing research of CRN.After that,we summarize and analyze the scenario design patterns of routing research from four aspects:medium,channel,node and network;study and discuss the main research productions from the views of optimization scheme and routing topology algorithm/protocol in detail at the end of this paper.
