In this paper, the authors propose a backbone construction scheme for Multi-hop Wireless Cognitive Radio Networks (MWCRN) with a channel bonding technique. In their proposed scheme, the backbone is established purely in licensed bands using Cognitive Radio (CR) technology. They introduce a channel bonding technique to get higher performance of the network. To get higher reliability of MWCRN, they use backup channels in their proposed scheme. The proposed scheme includes two major steps. The first step is to formulate a backbone network; and the second step is to assign operating channels and backup channels to each backbone link. Simulation results show that the proposed scheme achieves higher network performance of multi-hop wireless cognitive radio networks.
