An approach to evaluate trust and reputation of things in a Multi-IoTs scenario

In the past research, trust and reputation have been investigated for communities of people, for organizations and for multi-agent systems. However, in the last few years, things are becoming increasingly relevant in the Internet scenario and, at the same time, increasingly complex. As a matter of fact, the term “Internet of Things” (hereafter, IoT) is becoming more and more common in both the scientific and the technological contexts. But, if a thing can have a profile and a behavior like a human, it is not out of place to extend the concept of trust and reputation to things and to define ad hoc approaches for their computation. In this paper, we investigate trust and reputation of a thing in a Multiple IoTs scenario and we propose a context-aware approach to evaluate them. This task is not immediate because it should consider all the peculiarities of a thing compared to a human and all the specificities of a Multiple IoTs scenario compared to a community of people.
