Industrial Internet of Things: Specificities and Challenges

Résumé

More than one decade ago emerged the Internet of Things (IoT) paradigm, which enabled new applications to be incorporated in our everyday life. We have now a large variety of radio technologies (e.g., IEEE Std 802.15.4-2015, Bluetooth, WiFi, LoRa, Z-Wave) to connect more and more smart objects. Wireless technologies have evolved to address best effort scenarios in which reliability is traded-off by bandwidth and data rate. The specific requirements imposed by industrial applications are not comparable to mass-market needs driven by the demand of broadband and massive connectivity oriented to end user services and applications. Latency, reliability and energy consumption requirements did not consider the critical operation of industrial assets, which have been left aside and operated by wired buses for the last 30 years. This has shaped the way industries are today and limited solutions in which mobility or the lack of wires would have facilitated production processes. Yet, and understanding that industries equipment is built to last for more than 30 years, wireless could have been seen as a perfect tool to extend and instrument legacy equipment. However, the objectives of the standardization bodies and manufacturers aimed to address other more relevant areas, in which reliability was a secondary objective. We face to a huge variety of potential applications in the industrial space, including System Automation, Wireless Control, Predictive maintenance and anomaly detection among others 1. Considering the requirements in terms of reliability, bounded jitter and delay and efficiency, research and standardization are still required to overcome current technological barriers. We need to tackle the problems of adaptability and compatibility to legacy technologies, the standardization barriers and the lack of trust to digital technologies from the industrial sector 2. Therefore the development of the Industrial IoT is tighten to the advances in ICT technologies in directions that diverge from those developed during the IoT and WSN hypes, opening new research and development opportunities this time, driven by already existing applications whose functionality needs to be broadly extended. 2 KEY CHARACTERISTICS OF WIRELESS INDUSTRIAL NETWORKS Wireless transmissions create specific challenges to tackle. Indeed, we need to redesign the algorithms and protocols that were invented to work properly in wired networks where, everything is finely controlled.
