Abstract
We consider a multi-destination two-hop untrusted amplify-and-forward (AF) relay networks, where each node is equipped with a single antenna and the confidential information communication needs the aid of the untrusted relay over the Nakagami- channel. Because the relay is energy-constrained, the relay needs to harvest energy from the received information and the jamming signals by applying the power splitting relaying (PSR) protocol. The confidential information can be protected from the untrusted relay eavesdropping with destination-aided cooperative jamming. We focus on the secure and reliable performance of the presented system. The secrecy outage probability (SOP) and the connection outage probability (COP) are specially examined, which mainly show in the closed-form expressions of SOP and COP. In addition, the effective secrecy throughput (EST) performance is also investigated to comprehensively measure the secure and reliable performance. Moreover, we also present the asymptotic analysis of EST at the high signal-to-noise ratio (SNR). The Monte Carlo simulation is applied to validate the accuracy of the derived expressions and reveals the effects of different parameters, such as the transmit SNR, the power allocation factor, the fading factor and other parameters on the EST.
