Abstract
Due to the limitation that the global positioning system cannot be used in indoor settings and the increasing demand for location-based services in indoor environments, indoor localization has become one of the hottest research topics in recent years. A variety of techniques have been proposed for indoor localization. This review paper aims to provide an overview of working principles of radio frequency identification based, Wi-Fi based and visible light localization techniques and their applications. The paper also presents a comprehensive analysis of the advantages and disadvantages of each technique, including their accuracy, cost-effectiveness, and ease of deployment. In the end, the paper predicts a few future research directions and potential opportunities for indoor localization. This paper will be of interest to researchers, practitioners, and industry professionals working on indoor localization and related fields.
