Cognitive radio networks (CRNs) has been popular in the field of wireless network. In CRNs, researches focus mainly on the single hop scenes rather than multi-hop networks. Studies for cognitive routing are also scarce. A new routing scheme is proposed based on path combination that communicating pairs share the links for all nodes. The cognitive networks are divided into two sub-networks: data network and control network. Each of the two network forms has their own missions. Spectrum resources are divided into conflict units and carefully allocated to links. The concept of price and spectrum blocks is used to judge the shared links. This scheme is good in performance because of the reduction of network load. With the combination of paths, spectrum resources will have a very high utilization rate.
