A network of relationships link individ- uals, who form (often overlapping) communities. They play speciic roles in their communities and rely on other members to get what they need but can’t obtain by themselves. This is the underlying rationale that has led to the social Internet of Things (SIoT). 1 In the SIoT, objects establish social-like relationships with each other. The re- sulting network of relationships is structurally navigable, enabling searches for speciic services in effective and ef icient ways. Furthermore, by leveraging social relationships,
