Secure outage probability of cognitive radio network relying non-orthogonal multiple access scheme

Abstract

This paper studies the secondary network relying relay selection to transmit signal from the secondary source (base station) to two destinations. Especially, two destinations are required non-orthogonal multiple access (NOMA) scheme and it benefits to implementation of the Internet of Things (IoT) systems. However, eavesdropper over-hears signal related link from selected relay to destination. This paper measure secure performance via metric, namely secure outage probability (SOP). In particular, signal to noise ratio (SNR) criterion is used to evalute SOP to provide reliable transmission to the terminal node. Main results indicates that the considered scheme provides performance gap among two signals at destination. The exactness of derived expressions is confirmed via numerical simulation.

“…Recently, many studies have been proposed for physical layer security (PLS) techniques in the fifth generation (5G); however, due to complex limitations, some of these solutions cannot be applied in IoT networks. NOMA is considered a viable technology to solve latency and connectivity requirements in IoT [23]- [27]. In [28]- [31], the authors have applied a NOMA with implementation of signal processing on the downlink side.…”
