摘要：

The rational spectrum resource allocation is one of the goals of Cognitive Radio (CR) technology. With the rapid increase of Secondary Users (SUs) numbers, the precise and real-time management becomes more and more difficult to achieve. In order to solve this problem, a hierarchical Cognitive Radio Network (CRN) architecture that several administration entities focus on providing spectrum services for users of variety tiers is proposed. The corresponding resource allocation algorithm based on stable matching in this architecture is also given. This algorithm guarantees the restriction on SUs' transmission power for Primary Users (PUs), and also considers both utility functions of users. Simulation results demonstrate that the proposed method can roughly achieve the same performance of optimal solution with lower computation complexity and system delay. © 2016, Science Press.
