Cognitive Radio (CR) is an emerging technology for future wireless communication and technology. In the existing system, there is a multiple allocation over all the bands and also there is a crisis for spectrum availability, therefore a new approach for spectrum licensing is needed. Hence the optimal solution for the above case is cognitive radio. The resource-allocation problem in multi-hop CR networks is modeled as a multi-commodity flow problem. To solve this problem, the queue-balancing flow control method is proposed.
