Cognitive Radio (CR) enables the efficient utilization of the limited radio spectrum, network resources and an unlicensed user can communicate in licensed spectrum without interfering a licensed user. In CR expected to address several operational challenges such as spectrum access in dynamic manner, providing Quality Of Service (QOS) between end-to-end and spectral heterogeneity. Hence it become an all-encompassing term for a wide variety of technologies and emerges as a promising solution to improve current spectrum utilization efficiently. In this paper, the authors proposed spectrum mobility management in cognitive radio.
