Many Industrial IoT TSCH networks, such as SmartMesh IP, operate in the same 2.4 GHz frequency band as WiFi. As the smart factory becomes more and more connected, WiFi starts being rolled out on many factory floors. It is hence completely legitimate to question whether WiFi impacts Industrial IoT TSCH networks, and in particular their endto-end reliability. In a setup which replicates a worst case industrial setting, we conduct a thorough experimental study which looks at the performance of a 47-mote SmartMesh IP network undergoing several levels of WiFi interference. The result is that, even though the latency and power consumption of the network increase, end-to-end reliability stays at 100% even under very high WiFi interference. The conclusion is that TSCH technology at 2.4 GHz, such as SmartMesh IP, is perfectly appropriate to for an industrial environment where WiFi is heavily used. This paper is complemented by a research report which contains all the information needed to replicate the measurements, and the raw data.

Summary The vision to connect everyday physical objects to the Internet promises to create the Internet of Things (IoT), which is expected to integrate the diverse technologies such as sensors, actuators, radio frequency identification, communication technologies, and Internet protocols. Thus, IoT promises to transfer traditional industry to advance digital industry known as the Industry 4.0. At the core of the Industry 4.0 are the wireless sensor networks (WSNs) and wireless sensor and actuator networks (WSANs) that led to the development of industrial wireless sensor networks (IWSNs) and industrial wireless sensor and actuator networks (IWSANs). These networks play a central role of connecting machines, parts, products, and humans and create a diverse set of new applications to support intelligent and autonomous decision making. The IWSAN is a promising technology for numerous industrial applications because of their several potential benefits such as simple deployment, low cost, less complexity, and mobility support. However, despite such benefits, they impose several unique challenges at different layers of the protocol stack when deploying them for various monitoring and control applications in the Industry 4.0. In this article, we explore IWSAN, its applications, requirements, challenges, and solutions in the context of industrial control applications. Our main focus is on the medium access control (MAC) layer that can be exploited to satisfy such requirements. Our discussion presents extensive background study of the MAC schemes and it reviews the MAC protocols of the existing wireless standards and technologies. A number of application‐specific MAC protocols developed to support industrial applications, which are not part of these standards, are also elaborated. We rationalize to what extent the existing standards and protocols help in solving such requirements as laid down by the Industry 4.0. In the end, we emphasize on existing challenges and present important future directions.

“…Adopting TSCH, a comparison with adaptive singlechannel routing techniques in [6] has shown superiority of channel hopping in sparse networks. In [7], the authors have compared scheduled and random access-based MAC for multihop TSCH, and have shown that they deliver similar reliability for low-load networks. While these studies provide insights into the benefits of channel hopping, they do not address design of the hopping sequence.…”

Abstract-Guaranteeing reliability in highly interfered environments is a challenging requirement of current and future wireless applications. A promising state-of-the-art solution for low-power wireless technologies, e.g., wireless sensor networks (WSNs), is frequency hopping aided with black-and white-listing of channels. Both methods, although increase reliability, sacrifice frequency resources. Extensive measurements of channels' packet drop probabilities show that interfered channels are not fully blocked. Motivated by this discovery, we propose the whitening -a methodology for reliable hopping sequence design without resource sacrifice. We model the efficiency of interfered ISM band channels, and study the gains and trade-offs of applying whitening in different scenarios. Application reliability is achieved by granting re-transmissions within a time deadline. Simulations and measurements, performed on the exemplary use case of Time Slotted Channel Hopping WSNs, show that the proposed methods outperform state-of-the-art solutions in the presence of interference in terms of reliability.
