Routing of Cognitive Radio Networks:A Survey
Zhigang Cao · Dianzi xuebao · 2010
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.
