Cognitive Radio Networks (CRNs) have been obtained a significant focusing due to the ability of this technology to dissolve the issues of spectrum overcrowding and underutilization. In a CRNs, the secondary user (SU) is equipped to discover and use abandoned licensed channel, however, they must be desertion the channel if any interference is brought to the primary user (PU) who holds the channels. For that, the dynamic spectrum access (DSA) in CRNs is considered as an important application that allows for SU to use the licensed band in a dynamic way. Nevertheless, there are several challenges on CRNs such as interference, channel selection, routing, and etc. Cross-layer design can provide effective solutions in order to counteract these challenges. To this aim, in this paper, we have studied the existing related work about applying a cross-layer design in CRNs and how the upper layers and the lower layers parameters can optimize with the helping of a cross-layer. Finally, we have explained the implementation challenges of cross-layer design on CRNs.
