Smart homes in the Era of Sustainability and Digitalization: A Bibliometric Review

Smart home research has expanded rapidly alongside advances in IoT, AI, and energy systems. We compile and deduplicate a 2000–2025 corpus of 3,020 records from Web of Science and Scopus and apply a transparent bibliometric workflow (bibliometrix/VOSviewer) to map publication dynamics, core outlets, collaboration networks, and conceptual clusters. Output accelerates after 2010 and concentrates in open-access, engineering-oriented journals. Co-occurrence analysis reveals four stable themes: (i) IoT infrastructure and ambient intelligence, (ii) energy management and smart grids, (iii) automation and intelligent building systems, and (iv) AI-based pattern recognition. We also document a shift from standalone automation to socio-technical, energy-aware ecosystems and outline practical implications around interoperability, privacy-by-design, and household-grid integration. All search strings, export settings, and cleaning rules are released for replication.
