For the better improvement of spectrum utilization, in this paper, we propose a novel spectrum management and sharing models. For specification, the concept of spectrum database and anxiety level of idle spectrum resource are introduced in dynamic spectrum management model. Accordingly, the QoS requirements are formulated in the spectrum sharing model. In addition, we introduce a multi-hop spectrum relay service scheme that can decrease the spectrum sharing complexity in applications and can be regarded to be more practical and scalable. To improve the spectrum utilization and revenue, the spectrum sharing strategy is combined with the anxiety and matching level of idle spectrum. The simulation results validate that our approach can achieve a high level performance, especially the spectrum sharing revenue.
