| Abstract(in English) | In this paper, we have studied the methods of detecting low Signal to Noise Ratio (SNR) nodes by outlier detection in cooperative spectrum sensing. In many studies in the field of cooperative sensing, it is assumed that an average received energy among sensing nodes is equal. However, in practical wireless environment, the performance of cooperative sensing system with low SNR nodes is severely degraded due to influence of multipath fading. The goal of this research is to detect the low SNR nodes and minimizes the impacts caused by these low SNR nodes to the cooperative sensing performance. Therefore, we propose an outlier detection algorithm to exclude low SNR nodes from cooperative sensing nodes by using past accumulated energy data. Several outlier detection methods are compared, and a suitable algorithm for the low SNR node detection method is selected. In addition, the required length of estimation period for the outlier detection is revealed. |
