Monitoring solution for autonomic Middleware-level QoS management within IoT systems

Nowadays, the Internet of Things (IoT) paradigm is expanding immensely. It brings ubiquitous intelligence through the interconnection of equipment (sensors, devices, etc.) to the Internet, allowing the birth of a new era of applications in various fields. One of the main challenges to be considered in the IoT is the Quality of Service (QoS) issue. Aiming to support the vision of an autonomic Middleware-level QoS management for IoT systems, this paper proposes and validates a functional architecture of a monitoring component for the detection of QoS degradation. We also demonstrate the benefits that could be gained from simple QoS-oriented adaptation actions dynamically executed to overcome the detected degradations.
