Abstract
In recent years, with the emerging wireless technologies, more spectrum bands are needed compared to before. Related to this fact, Cognitive Radio (CR) is one of the technologies used for effective spectrum management. In addition, regarding the sharing rules of the Licensed Shared Access (LSA) technology, secondary and primary users can use the spectrum band in the controlled environment. In this work, an overbooking technique is used by LSA and CR technologies. Based on LSA sharing rules, the overbooking Spectrum Manager (MNO) allows the network to accept more reservations than capacity. In this study, network performance analysis is presented while analyzing the overbooking reservation limits based on the activity rates of the primary and secondary users. Simulation results show the network revenue, spectrum utilization, overbooking reservation limit, and rejected secondary user rates. Finally, the simulation results tradeoff between the performance of overbooking and the non-overbooking reservation methods.
