  text: The integration of social networking concepts into Internet of Things systems
    is a burgeoning topic of research that promises to support novel and more powerful
    applications. In this paper we focus on the design and implementation of a highly
    scalable Trust and Reputation Model for the Internet of Things based on the social
    approach that the COSMOS project introduces, as part of its final results. We
    create our model by combining popular solutions proposed for Peer-to-Peer and
    mobile ad-hoc networks and adapting them on the Internet of Things concept. Each
    Thing can compute the Trust index of another Thing based on its own experiences,
    while it has the capability of determining its Reputation Index either by consulting
    its other “friends” (Followees) or referring to the Platform, a management system
    used in COSMOS. The model is tested through simulations of the proposed social
    system, demonstrating the ability of TRM-SIoT to achieve the Social Exclusion
    of malicious nodes and collectives from the network, with low computational overhead
    and high scalability. Furthermore, due to the adaptive nature of the system, Social
    Reintegration of these nodes is also possible.
