The social internet of things (SIOT) is a thriving research field that emerged after the integration of social networking concepts in the internet of things. It resulted in the appearance of new and more powerful applications. Indeed, trust management system (TMS) has been considered as an effective security mechanism in the Internet of things. Thus, many research works have been carried to propose trust evaluation and trust prediction methods. In the traditional trust management system, historical behavior data are taken into account to predict the trust value of the network entity, while the context of the network entity is rarely considered. The novelty of our approach can be summed up in three aspects: i) designing a highly scalable trust model, ii) the ability of the system to provide the most trustworthy service provider which takes into account the dynamic aspect of the internet of things, such as context, the capacity object and the social relationship between objects, iii) and the application of decision tree to analyze first the relationship between the different components of the network and the object behavior, and to improve then the decision making.
