Evolution of Consumer IoT: A Bibliometric Study of Research Trends and Knowledge Diffusion

Abstract

The Internet of Things (IoT) has transformed everyday life through the use of smart technologies and there is tremendous scope of such advancements in consumer product development. Hence it requires a structured understanding of research patterns, obstacles, and possibilities in the field of Consumer Internet of Things (CIoT). This research presents the first thorough bibliometric CIoT studies, assessing 589 articles indexed in Scopus (2000–2024) to illustrate the intellectual framework, pinpoint significant contributors, and shed light on emerging topics. Using R Studio (Biblioshiny) and Excel, the findings indicate an increase in publications after 2015, fueled by growing interest from both academic and industry sectors worldwide. While the United States, India, and the United Kingdom are at the forefront of publication output, East Asian countries demonstrate superior research impact. Prominent topics like automation and smart homes are contrasted with less explored areas like privacy, ethical AI, and sustainable IoT solutions. Journals like "Sustainability" have emerged as key players, although insufficient international collaboration highlights the necessity for partnerships beyond borders. The research identifies critical shortcomings in interdisciplinary studies, frameworks for consumer trust, and sustainable IoT solutions. By providing a foundational overview of the progression of CIoT, this study assists scholars in navigating future research pathways, advocating for improved collaboration, significant studies, and socio-technical innovations to serve as a fundamental resource for researchers and practitioners in aligning progress with societal demands and ethical considerations.
