Guest Editorial: Blockchain and Industry 4.0 in Resilient Wireless Communications

In the era of Industry 4.0, Internet of Things (IoT) technologies play an important and enabling role. IoT technologies support the capture (and increasingly processing) of data close to the point of data capture, and can be used as a basis to establish a sustainable model for cities and to preserve the quality of life of citizens. However, the implementation of Industry 4.0 still requires experimentation to evaluate potential economic impact and benefit. This stands particularly true in the face of data explosion, with faster data transfer rates across wireless communications (e.g., increasing availability of broadband, and 5G and beyond, 5G&B, networks) and the ability to support real-time decision making based on the collection and analysis of this data. Moreover, there is a need to transform the workforce, for example, integrating system operators with new skills to manage work digitally.
