Learning, Computing, and Trustworthiness in Intelligent IoT Environments: Performance-Energy Tradeoffs

Abstract

An Intelligent IoT Environment (iIoTe) is comprised of heterogeneous devices that can collaboratively execute semiautonomous IoT applications, examples of which include highly automated manufacturing cells or autonomously interacting harvesting machines. Energy efficiency is key in such edge environments, since they are often based on an infrastructure that consists of wireless and battery-run devices, e.g., e-tractors, drones, Automated Guided Vehicle (AGV)s and robots. The total energy consumption draws contributions from multiple iIoTe technologies that enable edge computing and communication, distributed learning, as well as distributed ledgers and smart contracts. This paper provides a state-of-the-art overview of these technologies and illustrates their functionality and performance, with special attention to the tradeoff among resources, latency, privacy and energy consumption. Finally, the paper provides a vision for integrating these enabling technologies in energyefficient iIoTe and a roadmap to address the open research challenges.

AI explainability and governance in smart energy systems: A review

“…It captures various dimensions of "IoT and Edge," including detecting power consumption attacks for promoting vehicular edge devices reliability and AI chips' trustworthiness (Zhu et al, 2022), enabling sustainable energy and ethical stable power applications by self-powered, learning sensor systems (Alagumalai et al, 2022), and improving the data exchange for mobile sensors to increase the energy efficiency and trustworthiness of the IoT network (Haseeb et al, 2022). Additional dimensions include efficiency in energy use via trustworthy intelligent IoT environments (Soret et al, 2022), cloud computing to monitor Wireless Sensor Network (WSNs), cloud and edge computing in energy systems applications, IoT devices in the power network, edge-cloud computing in energy monitoring, and edge computing for IoT energy systems.…”

Analysis of Distributed Ledger Technologies for Industrial Manufacturing

“…This results in an increasing number of smart devices with sensors and actuators that are being integrated in industrial automation processes. In parallel, local edge computing infrastructures are being built up in manufacturing plants, which provide resources for advanced computing and henceforth the basis for next generation IIoT applications [2]. The key economic driver behind this technological evolution is the increase in the production flexibility.…”
