“…Later, Chen and others expanded their previous security works to cognitive relaying networks [15,16]. The relay design in previous works [15,16] exploits the maximum ratio combining/zero forcing beamforming scheme to guarantee the secrecy performance of dual-hop short-packet communications. In the underlay cognitive relaying network of Ho and others [17], secondary-source and secondary-energy-harvesting relays send short packets to a secondary destination under interference constraints.…”

“…Their proposed protocol lowers the latency and improves the reliability from those of the benchmark scheme (long packet communications created in the same model settings). However, previous works [14][15][16][17][18][19] have ignored the emerging IRS.…”

“…Recently published works [14][15][16][17][18][19] have focused on short-packet communication cognitive radio networks. Cognitive radio is a spectrum-sharing solution between primary users in primary networks and secondary users in secondary networks, allowing the efficient use of licensed spectra in primary networks.…”

We propose short packet communication in an underlay cognitive radio network assisted by an intelligent reflecting surface (IRS) composed of multiple reconfigurable reflectors. This scheme, called the IRS protocol, operates in only one time slot (TS) using the IRS. The IRS adjusts its phases to give zero received cumulative phase at the secondary destination, thereby enhancing the end‐to‐end signal‐to‐noise ratio. The transmitting power of the secondary source is optimized to simultaneously satisfy the multi‐interference constraints, hardware limitations, and performance improvement. Simulation and analysis results of the average block error rates (BLERs) show that the performance can be enhanced by installing more reconfigurable reflectors, increasing the blocklength, lowering the number of required primary receivers, or sending fewer information bits. Moreover, the proposed IRS protocol always outperforms underlay relaying protocols using two TSs for data transmission, and achieves the best average BLER at identical transmission distances between the secondary source and secondary destination. The theoretical analyses are confirmed by Monte Carlo simulations.

“…Meanwhile, [18] performed the decoding error rate evaluation, optimal blocklength, and optimal RL allocation for the unmanned aerial vehicle-based DF three-hop relay IoT networks. In [19], the secrecy throughput of dual-hop relaying CR SPC IoT networks was analyzed under the constraints of secrecy and the decoding error probability, where the DF relay utilizes either the MRC or zero-forcing beamforming scheme. [20] investigated TAS/MRC and TAS/selectioncombining (SC) MIMO systems with SPCs to gain the advantages of connectivity, SE, and uRLLCs.…”

<p>In this work, we investigate short-packet communications for multiple-input multiple-output underlay cognitive multihop relay internet-of-things (IoT) networks with multiple primary users, where IoT devices transmit and receive short packets to provide low-latency and ultra-reliable communications (uRLLCs). For performance evaluation, the closed-form expressions of the end-to-end (E2E) block error rate (BLER) for the considered systems are derived in a practical scenario under imperfect channel state information of the interference channels, from which the E2E throughput, energy efficiency (EE), latency, reliability, and asymptotic analysis are also studied. Based on the analytical results, we adapt some state-of-the-art machine learning (ML)-aided estimators to predict the system performance in terms of the E2E throughput, EE, latency, and reliability for real-time configurations in IoT systems. We also obtain the closed-form expressions for the optimal power-allocation and relay-location strategies to minimize the asymptotic E2E BLER under the proportional tolerable interference power and uRLLC constraints, which require negligible computational complexity and offer significant power savings. Furthermore, the ML-based evaluation achieves equivalent performance while significantly reducing the execution time compared to conventional analytical and simulation methods. Among the ML frameworks, the extreme gradient boosting model is demonstrated to be the most efficient estimator for future practical IoT applications.</p>
