“…For the channel settings, the variance of each residual SLI link is set, based on the measurement results in [35] and the assumption in [36], i.e., Ω k = −13 dB, ∀k. 3 We consider a simplified path-loss model with λ k = d −η k , where η = 3 represents the path-loss exponent corresponding to urban areas and d k denotes the distance between R k−1 and R k [37]. Let D = 1 denote the normalized transmission distance between the source and destination and assume equal distance allocation, i.e., d k = D/ (K + 1).…”

In this study, we investigate multihop multiple-input multiple-output (MIMO) full-duplex relay (FDR) networks with short-packet ultra-reliability and low-latency communications (uRLLCs), where transmit-antenna selection/maximum-ratio combining and transmit-antenna selection/selection combining are leveraged as diversity techniques. Under quasi-static Rayleigh-fading channels and the finite-blocklength theory, the end-to-end block-error rate (BLER) performance of the considered FDR is analyzed and compared with that of half-duplex relaying systems, from which the effective throughput (ETP), energy efficiency (EE), reliability, and latency are also investigated \textcolor{black}{to comprehensively capture the performance trend of the considered systems. To analyze the diversity order and} gain further insights into the system design, an asymptotic BLER analysis in the high signal-to-noise ratio regime is provided. However, the derived analytical expressions contain non-elementary functions, making them intricate for practical implementations, particularly in real-time configurations. Therefore, we have introduced a deep multiple-output neural network with short execution time, low computational complexity, and highly accurate estimation to overcome this hurdle. This network can serve as an efficient tool to rapidly respond to the necessary system parameters, such as transmit power and blocklength, when the services request specific ETP, EE, reliability, and latency. To corroborate the correctness of the theoretical analysis, extensive simulation results are provided under varying impacts of system parameters, e.g., numbers of channel uses, information bits of data, relays, and antennas.

In this study, we investigate multihop multiple-input multiple-output (MIMO) full-duplex relay (FDR) networks with short-packet ultra-reliability and low-latency communications (uRLLCs), where transmit-antenna selection (TAS)/maximum-ratio combining (MRC), TAS/selection combining, and maximum-ratio transmission/MRC are leveraged as diversity techniques.

To gain further insights into the system design, an asymptotic BLER analysis in the high signal-to-noise ratio regime is provided. Based on the analytical and simulation results, the gains of multihop MIMO FDR networks in the context of short-packet uRLLCs are confirmed via the effect of system parameters on network performance. In addition, a novel deep multiple-output neural-network framework is developed to simultaneously predict the ETP, EE, and reliability with high accuracy, low computational complexity, and short execution time. This makes the framework an efficient estimator for real-time evaluations of future IoT applications, compared with conventional analysis and simulation approaches.

“…They considered the integrated architecture for energy harvesting and the amount of harvested energy is not sufficient to transfer the data. Hu et al [26] suggested a novel EH technique based on discrete-time-switch (DTS) and PS protocols to increase the average energy transfer rate and information rate. They focused on energy transfer rate but not on energy harvesting capacity.…”

Simultaneous wireless information and power transfer (SWIPT) is recently emerging as one of the vital solutions to prolong the lifetime of energy constrained wireless sensor nodes. However, current works on SWIPT considered only the immediate past-hop node's RF signal as a source of energy harvesting in multi-hop Internet of things (IoT) networks. In case of weak radio frequency (RF) signal, the amount of harvested energy does not support for continuous communication. Hence, in this paper a new energy harvesting mechanism is proposed which considers multiple sources (MS) such as (1) sink broadcasting energy, (2) co-channel interference, (3) neighbor nodes' RF signal, and (4) immediate past-hop node's RF signal for energy harvesting. Towards such prospect, a new SWIPT architecture is proposed called hybrid SWIPT (H-SWIPT) by integrating time switching (TS) and power splitting (PS) architectures.Furthermore, an efficient route selection mechanism is introduced to minimize the total energy consumption of the path based on an energy cost metric. To validate the proposed mechanism, simulation experiments are conducted and obtained the superiority of H-SWIPT compared with existing methods in terms of average harvested energy. Further, the effectiveness of proposed method performance is investigated through energy cost at different node density and barrier rates.
