Abstract
This letter presents distributed algorithms that enable efficient spectrum sensing in cognitive radio networks. In the proposed setting, each node in the system detects different channels in a cooperative fashion in order to improve access to the spectral resources available to the cognitive radio network. The developed scheme utilizes a message-passing framework for efficient channel assignment. Simulation results establish that this class of algorithms outperform existing techniques and improves the overall sensing performance of the system.
