In this paper, we investigate physical layer security of multi-relay non-orthogonal multiple access (NOMA) networks with partial relay selection considering decode-and-forward (DF) and amplify-and-forward (AF) protocols. We propose a partial relay scheme aiming to select the best relay based on the highest signal-to-noise-ratio (SNR) of the ﬁrst link. We derive new exact and asymptotic expressions for strictly positive secrecy capacity (SPSC) and secrecy outage probability (SOP) considering Rayleigh fading channels. Numerical results demonstrate that AF and DF provide almost a similar secrecy performance. Moreover, they prove that partial relay selection improves SPSC and reduces SOP when the relay-cluster is closer to the legitimate receiver.

“…On the other hand, a more power is allocated to users with poor channel conditions to detect their own data by considering the information of the other users as noise [5]. To improve the performance of NOMA networks, cooperative transmission was introduced to NOMA in [6][7][8]. In [9], a hybrid decode-and-forward (DF) and AF protocol was analyzed in multi-relay NOMA system over Rayleigh fading channels.…”

In this paper, we investigate the physical layer security in cooperative non-orthogonal multiple access (NOMA) networks over Nakagamim fading channels. Both amplify-and-forward (AF) and decode-and-forward (DF) protocols are studied. More particularly, closed-form exact and asymptotic expressions for strictly positive secrecy capacity are provided considering NOMA-AF and NOMA-DF relaying systems. Numerical results are presented to justify the accuracy of the obtained theoretical analysis. These results show that NOMA-AF and NOMA-DF relaying networks have a similar secrecy performance.
