Dear Colleagues,

The Internet of Things (IoT) represents the new frontier of industrialization. Each "thing" within the network is uniquely identified by an individual Internet address, is accessible via the Internet and is able to interact with information systems.

By its definition, the IoT is a direct consumer technology while the Industrial IoT is its use in industrial environments, or what is called "Industry 4.0." Industry 4.0 (IIoT) creates opportunities for companies, production plants and also for entire sensor networks. Even more than in applications aimed at a common user, industrial applications are critical because it is necessary to guarantee high levels of reliability, performance, availability and security, of both the infrastructures and the data. Moreover, it is mandatory to guarantee a high level of safety for involved humans.

This Special Issue aims to gather innovative theoretical and practical contributions that highlight solutions with a high degree of dependability in critical applications of Industry 4.0 based on sensor networks, with particular reference to environmental monitoring, but not limited to it. Also within the scope of this Special Issue are research articles that present innovative and efficient techniques for assessing dependability in the reference context.

In this Special Issue, we are interested in high-quality submissions that mainly highlight dependable approaches for critical applications involving the use of sensor networks especially when used in industrial environments. Topics of interest include but are not limited to the following:

• Industrial IoT
• dependable sensor networks
• algorithms for dependable critical applications
• dependable infrastructures for critical applications
• effective technique for dependability evaluation
• protocols for dependable applications
• dependable sensor networks architectures
• dependable routing in sensor networks
• dependable wireless connectivity in sensor networks
