With the rapid advancements in wireless communication, the problem of scarce radio resources and the low spectral efficiency caused by the stationary spectrum sharing strategies restricts the evolution of the future mobile communication. For this purpose, cognitive radio (CR) emerges as one of the most promising inventions which can overcome the spectrum shortage and spectrum underutilization. As the primary objective of CR, spectrum sharing can make efficient use of the limited spectrum, eliminate the scarcity of frequency resources and improve the system utilization, hence playing an important role in improving the system performance of cognitive radio networks (CRNs), In this survey paper, the spectrum sharing in CR network is discussed in terms of sharing process and different sharing schemes. Furthermore, the comparison of different spectrum sharing strategies is concluded. Moreover, some applications of the spectrum sharing schemes in CR network, like smart grid, public safety, cellular network and medical area are also introduced. In addition, the research issues in the field of spectrum sharing are discussed as well.
