S2NetM: A Semantic Social Network of Things Middleware for Developing Smart and Collaborative IoT-Based Solutions

Abstract

The Social Internet of Things (SIoT) paradigm combines the benefits of social networks with IoT networks to create more collaborative and efficient systems, offering enhanced scalability, better navigability, flexibility, and dynamic decision making. However, SIoT also presents challenges related to dynamic friendship selection, privacy and security, interoperability, and standardization. To fully unlock the potential of SIoT, it is crucial to establish semantic interoperability between the various entities, applications, and networks that comprise the system. This paper introduces the Semantic Social Network of Things Middleware (S2NetM), which leverages social relationships to enhance semantic interoperability in SIoT systems. The S2NetM employs semantic reasoning and alignment techniques to facilitate the creation of dynamic, context-aware social networks of things that can collaboratively work together and enable new opportunities for IoT-based solutions. The main contributions of this paper are the specification of the S2NetM and the associated ontology, as well as the discussion of a case study demonstrating the effectiveness of the proposed solution.

ICT Tools for Open Educational Resources Used in an Open Distance E-learning Institution in the Fourth Industrial Revolution Era

“…All web developments have their role in the transformation of knowledge management of OER, starting from Web 1.0 (read-only, company focus, connected information, home page), Web 2.0 (read-write, community focus, connected people, social media, for example, blogs and wikis, etc. ), Web 3.0 (read-write execute, individual focus, connects knowledge, live streams, intelligent agents, semantic webs) (Noh 2023), and followed by Web 4.0, which makes the internet more user-friendly, efficient, personalised, interactive, intelligent, and collaborative (Pliatsios, Lymperis, and Goumopoulos 2023). Lastly, the latest is Web 5.0, which aims to provide a decentralised platform to users while also incorporating human emotions using artificial intelligence (Mourtzis 2023).…”

A Novel Semantic IoT Middleware for Secure Data Management: Blockchain and AI-Driven Context Awareness

“…Another work, [50], was proposed in this area, with a prime focus on resolving privacy and security issues, specifically concentrated on the message queuing telemetry transport (MQTT) protocol. Some of the recent works that have amalgamated the concept of semantic annotations in IoT middleware include GMSCA [51], S2NetM [52], and SEDIA [53]. GMSCA is a generic IoT middleware for smart city applications that targets to address challenges regarding heterogeneity, service management, and security.…”
