摘要：
In this paper, we propose a buffer-aided relay selection scheme with primary sensing ability in an underlay cognitive radio network. The proposed relay selection scheme is evaluated in terms of outage probability, compared with the conventional max-min and max-ratio relay selection schemes, through simulations. The results show that the proposed scheme significantly improves the outage performance with a low primary activity and a short sensing period.
