An overview of the internet of things (IoT) and irrigation approach through bibliometric analysis

Abstract

This study evaluates the status of the internet of things (IoT) application in irrigation practices by focusing on the research direction, leading countries and productive researchers. The data from this study was extracted from the Scopus database and analysed using a Publish or Perish and a VOSviewer software for citation analysis and bibliometric map, respectively. The present study reveals that rapid increment of the articles in the subject area began in year 2016 and continues growing until today. India become the most productive country (n = 271), followed by China (n = 88), Indonesia (n = 41) and Malaysia (n = 32) in this topic. The most three prolific authors in this subject area are Wenyan Wu (Birmingham City University, UK), Steve Attard (AgriTech Solutions, Australia), and Yvette Everingham (James Cook University, Australia). This study gives insights into an overview of current and frontier research in the application of the IoT in irrigation related approach. It provides an idea to researcher to contribute the knowledge in under explored research domain.
