Rapid developments in wireless communication technology has increased huge demand for spectrum bands. This has raised the problem of spectrum scarcity, to meet such demands we require dynamic allocation of the spectrum which can be provided by cognitive radio networks (CRNs). Cognitive radio network is an evolving network which empowers secondary users (SU) to opportunistically utilize the spectrum band allotted to a primary user (PU) and it also has capability to solve spectrum inefficiency and spectrum scarcity issues. Spectrum handover approaches can reduce the handover delay, avoid unwanted interference, reduce collision and utilize the channel optimally to enhance the overall performance of SU communication. Hence, these approaches play an important role in enhancing the system performance of cognitive radio networks (CRNs). In this survey paper, various approaches of spectrum handover in the CR network has been discussed. Furthermore, the comparison of spectrum handover approaches has been carried out on various parameters. Moreover, some applications of the reactive and proactive handover in the CR network and research challenges related to spectrum handover has also been discussed in this paper. The parameter for analyzing the performances of spectrum handover approaches are listed which determine the efficiency of these approaches. Finally, through graphical representation, handover delay and complexity of various handover approaches is compared.
