Cooperative spectrum sensing (CSS) is the key technology of cognitive radio networks (CRNs) to identify the available spectrum by achieving spatial diversity gain. However, the reporting overhead and the imperfect reporting channel significantly degrade the efficiency and performance of CSS. In this paper, we consider the reporting overhead and the effect of the imperfect reporting channel in the process of CSS. By means of the sequential idea and the differential advantage, we propose a reliable sequential 0/1 differential (SZ/OD) reporting mechanism, with aim of mitigating the negative effect of the imperfect reporting channel on CSS. Simulation results show that compared to the existing reporting mechanisms, SZ/OD requires fewer reports in support of a higher detection accuracy and is not affected by imperfect reporting channels.
