A Survey on Industrial Internet of Things (IIoT) Testbeds for Connectivity Research

Tianyu Zhang, Chuanyu Xue, Jiachen Wang, Zelin Yun, Natong Lin, Song Han

TL;DR

This survey maps the landscape of IIoT connectivity testbeds, categorizing them by deployed protocols (TSN, IEEE 802.15.4/802.11, and 5G) and by testbed type (general, OPC-UA-TSN, and wireless). It synthesizes representative platforms, hardware configurations, and performance metrics to illuminate benchmarking practices, research gaps, and emerging trends. By detailing resource-management, real-time communication, reconfiguration, power, and security considerations, the paper offers practical guidelines for researchers building IIoT testbeds for connectivity research. The work underlines the value of modular, multi-technology testbeds and private networks for validating industrial communications in Industry 4.0 contexts, with implications for standardization, replication, and industrial deployment.

Abstract

Industrial Internet of Things (IIoT) technologies have revolutionized industrial processes, enabling smart automation, real-time data analytics, and improved operational efficiency across diverse industry sectors. IIoT testbeds play a critical role in advancing IIoT research and development (R&D) to provide controlled environments for technology evaluation before their real-world deployment. In this article, we conduct a comprehensive literature review on existing IIoT testbeds, aiming to identify benchmark performance, research gaps and explore emerging trends in IIoT systems. We first review the state-of-the-art resource management solutions proposed for IIoT applications. We then categorize the reviewed testbeds according to their deployed communication protocols (including TSN, IEEE 802.15.4, IEEE 802.11 and 5G) and discuss the design and usage of each testbed. Driven by the knowledge gained during this study, we present suggestions and good practices for researchers and practitioners who are planning to design and develop IIoT testbeds for connectivity research.
