The CRN is a future generation wireless communication system that allows SUs to use the underutilized or unused spectrum, known as white spaces, in licensed spectrum with minimum interference to PUs. However, the dynamic conditions of CRNs (e.g., PUs' activities and channel availability) make routing more challenging compared to traditional wireless networks. In this tutorial, we focus on solving...
Cognitive radio network (CRN) has emerged as a promising solution to solve the problem of underutilization of licensed spectrum. It allows opportunistic access of unutilized spectrum (or white spaces) by unlicensed users (or secondary users, SUs) whilst minimizing interference to licensed users (or primary users, PUs). The dynamicity of channel availability has imposed additional challenges for routing...
