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 used to enable cooperation communicate through a common control channel (CCC). Such usage introduces conditions like channel saturation which degrades the overall performance of the network. Thus, exchanging control information is a major challenge in cognitive radio networks. Moreover the multi-channel hidden terminal problem will be another most important challenge in cognitive radio networks, in which the multi-channel hidden terminals can decrease the throughput and make much overhead even let the whole network invalidation. In this paper, there is a novel MAC protocol for resolve the multi-channel hidden terminal problem using a single interface which avoid the CCC.
