Image result for What is Social IoT? According to , the Social Internet of Things (SIoT) is defined as an IoT where things are capable of establishing social relationships with other objects, autonomously with respect to humans. In this way, a social network of objects is created.
Let us now discuss a new paradigm: social IoT (SIoT). Here, we consider social relationships between objects the same way as humans form social relationships (see ). Here are the three main facets of an SIoT system:(i)The SIoT is navigable. We can start with one device and navigate through all the devices that are connected to it. It is easy to discover new devices and services using such a social network of IoT devices.(ii)A need of trustworthiness (strength of the relationship) is present between devices (similar to friends on Facebook).(iii)We can use models similar to studying human social networks to also study the social networks of IoT devices.
