Abstract

Dynamic spectrum access (DSA) promises to resolve spectrum scarcity and low spectrum utilization caused by today's static spectrum access (SSA) policy. In DSA, secondary users dynamically search and access spectrum bands that are temporarily unused by primary users. In this paper, we propose a control-free DSA algorithm for cognitive radio networks (CRN). Our algorithm enables each CRN node to select its operation band without coordination and exchange of control messages with neighbors. The contribution of our algorithm is that such an independently selected band can reach neighbors with high probability, while streamlining control complexity and overhead in DSA. We develop an analytical model to evaluate performance. Numerical results show that our control-free DSA algorithm can achieve very good performance.
