Abstract

With the increase in technological innovations that have occurred in recent years, the Internet of Things (IoT) is increasingly present in our daily lives. More and more devices are connecting to the Internet, using different communication methods to carry out this intermediation. However, many devices do not have the necessary adaptation to work with low power consumption without losing connectivity. The present work aims to carry out a comparative study between the Wi-Fi, General Packet Radio Services (GPRS) and Long Range (LoRa) networks, seeking to find out which is the best network for a given device. With the same networks, a reliability study was carried out, using packet duplication diversities. As a result, it is possible to state that GPRS and Wi-Fi is not a good type of communication when one values energy efficiency, while LoRa presents better results. These results were obtained by using more than one type of communication at a time, in which all packets sent were received at the same time, even if one communication was used at a time, in addition, packet losses were perceived.
