A cognitive radio is designed for the utilization of unused frequency. The transmission opportunity of a cognitive node is not guaranteed due to the presence of primary users (PUs). The performance of Cognitive Radio Adhoc Networks (CRAHNS) will significantly degrade when there are faulty nodes in the network. To provide efficient fault tolerance in the sense of faster and efficient recovery from route failure in CRAHNS, in this paper we present a single and multipath routing protocol, that uses ondemand distance vector routing, called Ad hoc On-demand Distance Vector Routing protocol (AODV) and Ad hoc On-demand Multipath Distance Vector (AOMDV) Routing Protocol. The various QOS parameters have evaluated. Since here we initially discuss about the packet transmission over number of nodes with effective end-to-end delay. We also analyze its performance using Network simulator (NS-2) software tool for the simulation purpose to give effective result of cognitive radio ad hoc networks.
