Wise Objects for IoT (WIoT): Software Framework and Experimentation

Despite their expansion, Internet of Things (IoT) technologies remain young and require software technologies to ensure information management in order to deliver sophisticated services to their users. Users of IOT technologies particularly need systems that adapt to their use and not the reverse. To meet those requirements, we enriched our object oriented framework WOF (Wise Object Framework) with a communication structure to interconnect WOs (Wise Objects) and IoT. Things from IoT are then able to learn, monitor and analyze data in order to be able to adapt their behavior. In this paper, we recall the underlying concepts of our framework and then focus on the interconnection between WOs and IoT. This is enabled by a software bus-based architecture and IoT related communication protocols. We designed a dedicated communication protocol for IoT objects. We show how IoT objects can benefit from learning, monitoring and analysis mechanisms provided by WOF to identify usual behavior of a system and to detect unusual behavior. We illustrate our approach through two case studies in home automation. The first shows how a wise smart presence sensor learns on a classroom occupation. The second shows how a wise system helps us to see correlation among several WOs.
