Impact of IoT and SoS in Enabling Smart Applications: A Study on Interconnectivity, Interoperability and Quality of Service

The authors of the paper have recently been involved in various projects related to the Internet of Things (IoT) and its practical application in several fields. These areas include Industry 4.0, smart cities, and healthcare - with a focus on behavior change. The projects used up to date technologies such as IoT, Machine Learning, Big Data, System of Systems (SoS) and Cloud Computing among others. The authors have specifically focused on specific IoT and SoS architectures, aiming to support and illustrate a variety of use cases. In this context, SoS expands the use of localized cloud, improving integration and communication technologies. It is essential that these SoS provide reliable quality of service (QoS), which includes management and monitoring of various QoS attributes.
