Estudo comparativo da aplicação de modelos de propagação para a localização em ambientes indoor utilizando dispositivos Bluetooth Low Energy

Abstract

The growing use of smartphones and the advancement of location techniques allowed the emergence of several applications that use technologies such as GPS, BLE, and Wi-Fi for different purposes. For outdoor applications, GPS is the most familiar and used. However, other technologies need to be used for indoor environments due to the characteristics of this type of environment. In this context, BLE and Beacons technologies along with Propagation Models are used to help determine the location within an environment. This work aims to compare the three indoor propagation models: Log-Distance, ITU, and Distance-Partitioned with respect to their performance applied to a dataset. The results showed that the models were technically tied, so the Distance-Partitioned should be the best option due to a smaller number of parameters among the three.
