In this paper, a novel cooperative sensing based on local spatial distance sensing and reliability clustering scheme is proposed. Based on the signal propagation model, the distance between primary user and secondary user follows the logarithmic normal distribution. Then we propose a distance threshold to detect the primary user and put forward a reliability-based clustering cooperative sensing scheme, taking into account the accuracy and throughput. In time domain, different locations may have different sensing periods. Through theoretical formulations, we can conclude that the cluster numbers will influence the system detection performance. Compared with the conventional energy detection, the performance of cooperative sensing has been improved. Based on the accurate fixed position of primary users, the system throughput has been increased. |
