The cognitive radio networks (CRNs) enhance spectrum usage by imparting an authorized spectrum with CR gadgets. In CRANs, the routing protocol will be a very problematic task because of modifications interrupted connectivity & frequency spectrum caused by the activity of the primary user (PU). In this manuscript, a Novel Routing Protocol for Cognitive Ad-hoc Networks(NRPCAN) is introduced. The convention uses channel accessibility & makes various node disjoint routes among source & destination nodes. The suggested convention will be contrasted with FTCRP& SEARCH conventions. The presentation assessment is conducted through scientific examination and utilizing OPNET simulation. The execution of suggested protocol accomplishes an expansion in throughput of the network; other than it diminishes the route failure probability because of PU activity & mobility of node. We have discovered that NRPCAN method outcomes in 35% to 80% enhancement in throughput of the network, with sensible extra routing overhead & average packet delay. Because of the successful decrease of impact among PUs & cognitive users, the NRPCAN method outcomes in diminishing the path failure rate by 52% to 88%.
