“…Information in the second time-slot A cooperative SPC network is considered in Fig. 1, one source equipped with N antennas, i.e., S, intends to transmit the information to its destination, i.e., D, with the assistance of one single antenna AF relay, i.e., R. It is assumed that the interference only affects on the relay due to the difference of frequency bands used in different two time-slots [12,13,23,24,25]. Frequency channel reuse can enhance the spectrum utilization in wireless systems, however, this also poses challenges for devices that share the same spectrum, as they may generate co-channel interference.…”

In this paper, we evaluate short packet communication (SPC) for a cooperative system where one relay assists data transmission between one multi-antenna source and one single antenna destination with the presence of co-channel interference at the relay. Two transmission schemes, i.e., transmit antenna selection (TAS) scheme and beamforming scheme (BS), are considered. Based on metric of SPC, we derive the average block error rate (BLER) for the system in asymptotic and closed-form expressions for both schemes. In addition, a solution of optimal power allocation (OPA) to maximize end-to-end effective system throughput is proposed. Effects of parameters such as total transmit power, number of the source's antennas, number of co-channel interference, and packet length on the performance of the system are evaluated. Finally, the results reveal that the performance of the OPA scheme outperforms that of the benchmark scheme, i.e., equal power allocation solution, in terms of BLER and the effective throughput for both the TAS and BS schemes. Moreover, the performance of the system reaches to saturation value with more antennas at the source. The findings indicate that the TAS and BS schemes have the same performance in terms of both the BLER and the effective throughput.INDEX TERMS block error rate, cooperative system, co-channel interference, short packet communications. I. INTRODUCTIONRecently, short packet communication (SPC) has been considered as an important technique for achieving low latency in wireless communication systems, and it has been widely studied in literature. Several scenarios such as cognitive radio networks [1], device-to-device (D2D) networks [2], unmanned-aerial-vehicle (UAV) networks [3,4], relaying systems [5,6,7] have been investigated in SPC systems.Furthermore, many applications where the transmitter and destination nodes cannot communicate directly with each other. Relaying communication is a technique in wireless communication where an intermediate device is used to forward data packets between the transmitter and the receiver [8,9]. The relaying device, also known as a relay node or relay station, receives the information from the transmitter and re-transmits it to the receiver. Two well-known protocols such as decode-and-forward (DF), and amplify-and-forward (AF) [10,11] have been used in cooperative networks. An evaluation of the AF relay system performance with taking into account interference at the relay was discussed in [12]. Inspired by [12], outage performance of an AF system under

“…Although the performance of SWIPT-enabled networks as well as the PLS was well studied as provided above, the performance of SWIPT-assisted relaying networks is still in the infancy stage. Particularly, only a few works have investigated such an interesting problem [ 26 , 27 , 28 , 29 , 30 , 31 ]. For example, the work in [ 26 ] investigated both the security and reliability of the two-way cognitive relaying networks.…”

“…Nonetheless, this work does not take the support of either relay or jammer into consideration to enhance the system performance. The authors in [ 30 ] also investigated security and reliability issues in wireless sensor networks. Despite their exploration of multi-source wireless sensor networks, they did not incorporate a jammer to actively reduce the intercept probability.…”

This paper studies the security and reliability of the power splitting (PS)-based relaying in the Internet of Things (IoT) networks with the help of a jammer. Based on the considered system model, we derive outage probability (OP) and intercept probability (IP) under two distinguished schemes, namely, the static PS relaying (SPSR) scheme and the dynamic PS relaying (DPSR) scheme. More precisely, the PS ratio of the former is a constant number, while the latter is optimally adjusted in order to minimize the OP and counts only on the channel gain of the second hop. Numerical results are provided to not only verify the accuracy of the proposed mathematical framework but also identify the trends of both OP and IP with respect to several important parameters. Our findings unveil that the OP and IP have contradictory behavior with respect to the transmit power and number of sources. Moreover, the performance of the DPSR scheme is superior to that of the SPSR scheme.

Because of the openness of the wireless relay channel, the confidential information transmitted in the channel is very easy to be eavesdropped on by malicious eavesdroppers and cause information leakage. In specifically, a friendly jammer will transmit a jamming signal to confound an eavesdropper attempting to listen in on a relay transmission. For wireless relay networks using the Rayleigh fading channel model, this research proposes a physical layer security technique based on cooperative interference. In the system, we design two-time stages to realize the transmission of the source to the user. During the initial phase, the signal source transmits a composite signal to both the user and the relay. In the second phase, the confidential information is relayed and artificial noise is generated by friendly jammers to confuse eavesdroppers. Through our proposed method, we derive precise analytical expressions for the intercept probability (IP) and outage probability (OP). The correctness of the theoretical derivation is verified by numerical results and theoretical simulation.
