The spectrum scarcity problem, which was being faced by the traditional wireless sensor networks for the past few years, has finally been addressed with the advent of Cognitive Radio Sensor Networks (CRSN). This new promising technology can utilize the unused portions of the frequency spectrum opportunistically. Now the CRSN devices cannot only sense the unused spectrum but they can also allocate it to the secondary users present in the same geographical area. In this review paper, various aspects related to the spectrum management of CRSN are analyzed in multi-dimensional way. The research problems associated with CRSN are discussed and the enabling techniques have been reviewed. Finally, other open research problems related to this area are discussed. This paper help the researchers in this domain for further study and select their next milestone.
