Abstract In this work, we investigate short-packet communications in power beacon (PB)-assisted Internet-of-Things (IoT) networks, where an energy-constrained actuator first harvests energy from a dedicated PB, and then transmits confidential signals to a desired controller in the presence of an eavesdropper.We derive a closed-form lower bound approximation expression for the average achievable effective secrecy rate (AESR) click here over Nakagami-m fading channels.To gain more insights, we also present the asymptotic average AESR in the high signal-to-noise ratio (SNR) regime.Specifically, analytical results indicate that an average AESR floor appears with the increase of SNR.
Moreover, a low complexity one-dimensional search method is employed to maximize the average AESR by optimizing the energy harvesting kt196 torque converter length.Monte-Carlo simulations are provided to corroborate our analysis.
