Abstract
In recent years, a great number of applications in Internet of Things (IoT) have been developed. In this context, many methodologies and technologies are used for several frameworks, including indoor localization. In this field, as highlighted in recent years, one of the most important aims of modern indoor applications in IoT is to identify how to manage and correctly convey people flow. This study aims to investigate the most common methods, technologies and applications for indoor localization in IoT and analyze the major systems currently in use and the application of these solutions to actual conditions. Following this, we propose an innovative method to detect people flow in indoor location. Based on Bluetooth low energy (BLE) technology, in this paper we analyze the possibility to use our system for many kinds of applications. The first experimental results show good performance of our system.
Highlights
With the development of the Internet of Things, there has been an exponential evolution in the use and implementation of many smart devices
At the base of this development is the progress of technology that responds to these changes to allow interaction in a simple and direct way, with all devices, and with the needs of the smartphones market, the birth of so-called nearables,small devices equipped with sensors that activate in proximity to other devices by sending and/or receiving information via wireless connections, such as Wi-Fi and Bluetooth [4,5]
In order to better evaluate the indoor localization methodologies, it is necessary to take into account a set of metric parameters, such as precision, recall, accuracy and F1-score
Summary
With the development of the Internet of Things, there has been an exponential evolution in the use and implementation of many smart devices. At the base of this development is the progress of technology that responds to these changes to allow interaction in a simple and direct way, with all devices, and with the needs of the smartphones market, the birth of so-called nearables,—small devices equipped with sensors that activate in proximity to other devices ( the term nearable) by sending and/or receiving information via wireless connections, such as Wi-Fi and Bluetooth [4,5] Another important point of view highlighted during the last years is tracking people flow in indoor locations, such as, for example, museums, sports halls, theaters, etc. For indoor environments, the position is determined and represented using the coordinates of a Cartesian system, as we are not interested in determining the position according to the characteristics of the earth
