“…At H, the relay forwards the decoding of the signal to D and E. To improve the antieavesdropping ability, when H transmits information to D and E, the influence of artificial noise is also considered. In the actual communication system, due to the existence of CEEs at D, there will be some artificial noise and residual interference [42][43][44]. In summary, the information at D and E q can be written as 3 Wireless Communications and Mobile Computing where x HD and x HE q represent the actual signals transmitted to D and E q with Efjx HD j 2 g = Efjx HE q j 2 g = 1. x J HD and x J HE q are, respectively, denoted as the signals sent to D and E q with artificial noise.…”

This paper mainly describes the transmission reliability and physical layer security of multiantenna decode-and-forward relay networks over the κ - μ shadowed fading distribution. We consider the existence of residual hardware impairments (RHIs) and channel estimation errors (CEEs) at the same time. Firstly, we give the network model. On this basis, we analyze the reliability and security by deriving the exact expressions of outage probability (OP) and intercept probability (IP). To further verify and investigate the theoretical derivation, the approximate analysis of OP is obtained under the high signal-to-noise ratio. In addition, we also use an optimized antenna selection technology at the transmitter to improve the security performance. Finally, through the comparative study of theoretical simulation and Monte Carlo simulation results, the factors affecting network transmission and security are acquired. The interesting conclusion is that both RHIs and CEEs can increase OP and decrease IP; that is to say, the existence of RHIs and CEEs can reduce reliability and enhance security.

In this paper, we investigate the reliability and security performance of cooperative multi-relay systems, where both source and relay nodes are energy-constrained nonlinear energy harvesters, scavenging energy from a power beacon nearby. Our analysis is based on practical model since residual hardware impairments (RHIs) and channel estimation errors (CEEs) are considered. Aiming at improving the system efficiency, three representative relay selection strategies are considered: 1) random relay selection (RRS); 2) suboptimal relay selection (SRS); and 3) optimal relay selection (ORS). To characterize the security performance of the considered strategies, we derive closed-form analytical expressions of the reliability and security in terms of outage probability (OP) and intercept probability (IP). We further discuss the asymptotic expressions and scaling laws of OP with the number of relays. The IP is analyzed for non-colluding and colluding scenarios. The numerical results illustrate that: 1) There is a tradeoff between reliability and security, that is when the outage constraint is relaxed, the IP can be enhanced, and vice versa; ii) The outage performance of the ORS and SRS schemes outperform RRS, indicating that relay selection can enhance reliability performance; iii) There are error floors for the OP due to the CEEs; iv) Colluding eavesdroppers can enhance eavesdropping attacks by sharing their intercepted information; and v) Although RHIs and CEEs have deleterious effects on the OP, they can protect the information transmission against eavesdropping attacks.

“…To improve the secure performance, the R transmits artificial noise signal to D and E n at the same time. In practice, D cannot remove the artificial noise due to the CEEs, and there are some residual interference received at D [37][38][39]. Therefore, the received signals at D and E n can be expressed as:…”

In this paper, we investigate the secure performance of multi-antenna decode-and-forward (DF) relaying networks where the Nakagami-m fading channel is taken into account. In practice, the joint impact of residual transceiver hardware impairments (HIs) and channel estimation errors (CEEs) on the outage probability and intercept probability is taken into account. Considering HIs and CEEs, an optimal transmit antenna selection (OTAS) scheme is proposed to enhance the secure performance and then a collaborative eavesdropping scheme is proposed. Additionally, we present main channel capacity and intercept capacity of the multi-antenna DF relaying networks. More specifically, we derive exact closed-form expressions for the outage and intercept probabilities. To obtain useful insights into implications of parameters on the secure performance, the asymptotic behaviors for the outage probability are examined in the high signal-to-noise ratio (SNR) regime and the diversity orders are obtained and discussed. Simulation results confirm the analytical derivations and demonstrate that: 1) As the power distribution coefficient increases, OP decreases, while IP increases; 2) There exist error floors for the outage probability at high SNRs, which is determined by CEEs; 3) The secure performance can be improved by increasing the number of source antennas and artificial noise quantization coefficient, while as the number of eavesdropping increases, the security performance of the system is reduced; 4) There is a trade-off between the outage probability and intercept probability. secrecy outage probability (SOP) and strictly positive secrecy capacity (SPSC). Regarding the non-homogeneous fading environments, the authors in [11] explored the secrecy performance of Wyner's model over α − µ fading channels. With the help of moment matching method, the authors in [12] derived approximate expressions for the SOP and SPSC over κ − µ shadowed fading channels. On a parallel avenue, cooperative relaying is another promising technique to further improve the spectral efficiency and enhance the coverage of wireless networks [13-15], and thus it attracts plenty of researchers to investigate the security issues of cooperative networks [16-23]. In [16], the authors analyzed the secrecy performance of amplify-and-forward (AF) relay systems over generalized-K fading channels, where three metrics for the SOP, average secrecy capacity (ASC) and SPSC were analyzed. To improve the PLS against eavesdropping attacks, the optimal relay selection (ORS) scheme was proposed for AF and decode-and-forward (DF) relay networks and the intercept probability (IP) for the proposed scheme was derived in closed-form [17]. From the perspective of energy harvesting, the authors in [18] proposed a cooperative transmission scheme for the AF and DF relay networks under the condition of an eavesdropper, where the relays can harvest energy from radio-frequency (RF) signals of a source through power-splitting protocol. In the existing research results, the researchers discuss...
