Cognitive Radio Networks (CRNs) increase spectrum utilization by opportunistically sharing licensed spectrum with cognitive capable devices. There are many routing algorithms proposed for CRNs so far. Most of these algorithms discover single path from source to destination and consume considerable amount of bandwidth during route discovery. On the other hand, the multipath algorithms designed for AdHoc networks show significant improvements in bandwidth utilization by discovering multiple paths using one route discovery process. So, it is believed that such multipath routing algorithm provides substantially resilient behavior to the channel dynamism because multiple paths are discovered within single round of path discovery. In this paper, a multipath routing protocol for Cognitive Radio Network (CRN) is proposed. The protocol considers channel stability for route formation and finds multiple disjoint paths between two nodes. The proposed multipath protocol is compared with Cognitive AODV (CAODV). Result shows that the performance of the proposed protocol is better in terms of packet loss rate, route discovery latency, route discovery frequency, and average delay.
