Social Internet of Things: Interoperability and Autonomous Computing Challenges

Social Internet of Things (SIoT) is a promising interdisciplinary paradigm where Social Networks are integrated with the Internet of Things (IoT) enabling humans and devices to interact, share information, and to autonomously establish social relationships. In this way, SIoT is divided into two components, people and things, supporting the social relationship and collaboration between things-things and things-humans. The adoption and leveraging modern paradigm of the SIoT presents several advantages, including (but not limited to) better navigability in a dynamic network of billions of devices, trust and dynamic discovery of services, higher data access, and real-time decision making much effectively. Despite the benefits, due to the all-in-one nature of SIoTs, still, there are several challenges that should be addressed. In this paper, first, we present the basis of SIoT, such as definitions, main roles, key relationships, and structures. Next, we outline the major benefits of SIoT. Finally, we discuss the major challenges of SIoT, including interoperability and autonomous computing – self-adaptation, self-organization, self-management, and selfhealing – by reviewing the recent advancements and state-of-the-art works in this emerging field.
