We employ diffusion strategies to guide the estimation process and a reputation mechanism to encourage secondary users to participate in the sharing of information. Simulation results illustrate the performance of the proposed technique for spectrum sensing over cognitive radios.text::conference output::conference proceedings::conference paper
