This paper presents a novel energy-efficient Radio Frequency (RF) Energy Harvesting (EH) scheme for secrecy performance in Internet of Things (IoT) network using cooperative communication approach under dissimilar faded channel environments. We have combined the concept of Destination Based Jamming (DBJ) with power beacon aided EH in our model. This paper provides three scenarios when the links undergo rayleigh fading, weibull fading, and nakagami-q (hoyt) fading where the effect of fading on the secrecy performance has been examined. Closed-form expressions for Secrecy Rate (SR) and System Energy Efficiency (SEE) are derived for the given scenarios. Analytical expressions have been well substantiated through extensive simulation results. The comparative analysis of system performance in terms of SR with respect to some important system parameters has been shown for various conventional protocols i.e., Decode-and-Forward (DF), Amplify-and-Forward (AF) and Hybrid-Decode-Amplify-Forward (HDAF). Furthermore, our scheme has been compared with benchmark techniques such as Cooperative Relaying (CR) and Cooperative Jamming (CJ) to quantify the performance improvement. Theoretical analysis and simulated results reveal the improvement of our proposed Signal-to-Noise (SNR) based hybrid decode-amplify forward Cooperative IoT (CIoT) scheme over existing relaying schemes which are further validated through statistical analysis. Results also depict the impact of eavesdropper position on secrecy performance at different channel mean power values. Finally, the SEE has been addressed and the impact of power splitting factor and transmit beacon power on the secrecy performance on the proposed model has also been analyzed with respect to change in fading parameters.

Physical Layer Security in an Untrusted Energy Harvesting Relay Network

et al. 2019

The security performance in an amplify-and-forward dual-hop untrusted relay network is considered. It is assumed that the source and multiple destinations are equipped with multiple antennas, and the information transmission is aided by a single-antenna but energy-constrained relay. On the one hand, the relay can harvest the energy from its received signals by applying power splitting relaying and time switching relaying protocols and then forward the information to the destinations. To enhance the reliability performance, multiple destinations are exploited to receive the information simultaneously. On the other hand, the relay may be a potential passive attacker and eavesdrop the received information, but this kind of illegal activity may not be discovered by the sources. To investigate the security and the reliability performance, the secrecy outage probability (SOP) and the connection outage probability (COP) of the considered system are especially examined. In particular, the exact closed-form expressions of SOP and COP are derived. Since the SOP and COP are contradictory metrics, the effective secrecy throughput (EST) performance is further characterized to comprehensively examine the security and the reliability performance. Moreover, the asymptotic analysis of EST in high signal-to-noise ratio (SNR) regime is provided. The theoretical analysis and simulations reveal the impact of different parameters on the system performance, such as the transmit SNR, the power allocation coefficient, the antenna numbers, and other parameters. The Monte Carlo simulations are in excellent agreement with the theoretical expressions.INDEX TERMS Untrusted relay, energy harvesting, multiple antennas, performance analysis, power splitting relaying, time switching relaying.

“…Furthermore, an optimal level of transmitting power of one user is analysed for a given level of transmitting power by another user. A detail analytical treatment for developing a closed‐form expression of SOP under a general scenario of different transmit power by two users is presented in this study in contrast to only simulation‐based results for a specific case of equal power transmission by two users as in [22]. The allocation of power to both the relays is analysed in the case of signal transmission with equal and different transmit power of the sources.…”
