Examining the trend of the research on the internet of things (IoT): A bibliometric analysis of the journal articles as indexed in the Scopus database

Abstract

Studies related to the Internet of Things (IoT) has grown tremendously since 2010 even though this topic has been found published in Scopus since 1970. Several studies have been published in the Scopus database to analyse the trend in this topic. However, it does not account for the whole years (since 1970 up to 2019). This study employs a similar bibliometrics technique to study the trend in IoT by taking into account the first year it was published until today. Results show that this topic has grown extensively since 2010 until today. The top two journals are IEEE Internet of Things Journal and IEEE Access with more than 500 articles. This topic has been studied quite extensively in computer science and engineering discipline. Apart from IoT or “Internet of Things”, the top three keywords used are “wireless sensor networks”, “network security”, and “energy efficiency”. While most of the publications were written in English, the majority of the publications were contributed by Asian countries of which the English language is not their native language. The results of this study might contribute to the body of knowledge on providing comprehensive trend analysis of the studies related to IoT, which was published in the Scopus database from the year 1970 to 2019.
