Trends in IoT Research: A Bibliometric and Science mapping Analysis of Internet of Things

Internet of Things (IoT) is about augmenting the existing power of the Internet beyond computers and smartphones

to a whole range of other things, processes, and environments involving living or non-living species. It can bring life

to the objects and enable them to communicate. This study presents the bibliometric analysis and science-mapping

analysis on IoT. The data were extracted from the Web of Science (WoS) database from 1989–2019. In total 14,469

documents (articles, review, editorial material, proceedings, etc) were retrieved, which were further processed by

VOSviewer software to perform advanced bibliometric analysis and science-mapping analysis. This research

identifies the most productive or leading authors, countries, journals, institutions, keywords and to know their coauthorship pattern, co-citation pattern, bibliographic coupling pattern, the co-occurrence of keywords pattern in the

research area of IoT. Results showed that Joel J.P.C Rodrigues was the most productive author, the People’s

Republic of China was the most productive country, the Journal of EEE Access was the leading journal, Luigi

Atzori was the most cited author. The main keywords more frequently occurred were Internet of things, and Internet,

and Security. The analysis showed a collaboration relation between authors, countries and

institutions. The visualizations conducted on this topic offer exploratory information on current status and trends on

the scientific literature of IoT and provides insights for established and novice researchers in the understanding of

this research topic.
