Enhancing Physical Layer Security of DF Buffer-Aided Relay Networks With Small Buffer Sizes

IEEE Access, 2019
In this paper, we propose a novel max-weight secure link selection (MWSLS) scheme to enhance physical layer security of decode-and-forward (DF) buffer-aided relay networks. The MWSLS scheme can select the link with the largest weight among all secure and
