Abstract (2. Language): 
Nowadays, wireless communication has become the most popular communication. As the need of wireless communication applications is increasing, the demand for wireless spectrum is also increasing commensurately. So, the most important challenge is to share the licensed spectrum without interfering with the transmission of other licensed users. In the early days, the spectrum was assigned statically owing to remove the interference problem, and to do so, the fixed spectrum assignment policy was used. Because of the fixed spectrum assignment policy, the spectrum was not efficiently utilized and remained vacant most of the time. This problem can be solved with cognitive radio technology, which can lead to the full utilization of spectrum holes. Cognitive radio technology has the potential of being a disruptive force within spectrum management. It has been a promising technology to increase spectrum utilization through spectrum sharing between licensed users (primary users) and unlicensed users (secondary users). In this paper, we have put emphasis on spectrum management processes, sensing, mobility, Challenges, and sharing, The challenges, issues and techniques that are involved in spectrum management has been discussed in details.
