Cognitive networks enable efficient sharing of the radio spectrum. Multi-hop cognitive network is a cooperative network in which cognitive users take help of their neighbors to forward data to the destination. Control signals exchanged through a common control channel (CCC) to enable cooperation communication. But, using a common control channel introduces a new issue like channel saturation which degrades the overall performance of the network. Moreover, the multi-channel hidden terminal problem will be another important challenge in cognitive radio networks, in which the multi-channel hidden terminals can decrease the throughput, cause much overhead, and sometimes even make the whole network invalidated. In this paper, a novel MAC protocol to resolve the multi-channel hidden terminal problem using a single interface which avoid using the CCC.
