This research was carried out to provide a comprehensive bibliometric analysis of published research on Internet of Thing (IoT) in order to appreciate the trends and compare the publications contributions among different countries, institutions, authors, subject areas and other knowledge domains. The publications on the IoT were retrieved from Scopus database covering a period of 2009 -2018. A total of 9,367 articles were identified after different search steps. The analyses were conducted using bibliometric procedure. The largest number of publications were recorded in 2018 (3,712). The results further revealed that, China contributed the highest proportion of 3018(32.2%) publications, the USA was ranked second with total publications of 1348 (14.4%). The most productive journals of publications were IEEE Access and IEEE Internet of Things Journal with 465 publications each with total citation of 103,978. Similarly, the most productive authors were Yang, Laurence with 29 (h-Index 14), followed by Sangaiah, with 27 (h-Index) while Rodrigues is the least with 20 (h-Index). The top two authors has cumulative citations of 1,331. The bibliometric analysis of subject area revealed that, Computer Science with 2,987 (32%) followed by Engineering with 2597 (27.7%). However, among the top areas of research in IoT, business, management and accounting is ninth with a contribution of 188 (2%) publications only from 2009 to 2018. Additionally, affiliations, keywords, language, funding agencies information were clearly reported. Finally, this study provide an important inside for researchers in all the field of learning and serve as motivation for engagement in research activities as well as collaborations among scientist for meaningful research output.
