On the Performance of Intelligent Reflecting Surface Aided Industrial Internet of Things Networks

This paper considers an Industrial Internet of Things (IIoT) environment and explores the utilizations of Intelligent Reflecting Surface (IRS) panels to improve the reliability of data transmissions. The effect of boundary walls and reflected signals in an indoor IIoT setting are accounted for in the analysis. Two multi-IRS-aided schemes are considered, that is, Exhaustive IRS-aided (ERA) scheme and Opportunistic IRS-aided (ORA) scheme, and their performances are evaluated by analyzing the outage probabilities (OPs). Extensive simulation studies under-score the significant improvements in wireless communication performance and reliability brought about by deploying IRS panels in IIoT environments.
