Applications of IoT for achieving sustainability in agricultural sector: A comprehensive review

This research aims to achieve a holistic understanding of the current IoT scenario by conducting a comparative analysis of the prevailing literature regarding IoT applications in the agricultural domain. Also, it proposes a framework for IoT adoption in the case sector. A systematic literature review was conducted with a methodology that focused on scientific articles authored in the English language that were published in peer-reviewed journals in the last five years. Initially, 179 research papers were extracted from the SCOPUS database and finally, 82 relevant articles were considered for the study which were classified into various categories and studied thoroughly. Based on a comprehensive survey of the selected articles four research questions were identified and successfully addressed. The results highlighted that research efforts pertaining to IoT applications of agriculture have matured from their initial conceptual stage and now reached the implementation phase. Also, it was observed that Machine Learning based algorithms were utilized extensively in recent research studies. For the first time, an exhaustive study has been conducted holistically to comprehend the recent advances in the field of IoT applications for the agricultural sector.
