Um Estudo sobre a eficiência energética em sistemas IoT com diversidades de duplicação de pacotes

Abstract

The number of IoT devices has increased dramatically in recent years. It is estimated by 2025, 75 billion devices IoT connected to the Internet. Objects are increasingly connecting to the Internet, various types of communication can perform this intermediation. However, many of them are not adapted to work with low power devices without losing connectivity. This paper aims to conduct a comparative study between Wi-Fi, GPRS and LoRa networks to find out which option is best for the given device type. Using these networks, a usage study was conducted using various packet duplication diversities. As a result it can be stated that GPRS and Wi-Fi is not a good type of communication when it is energy efficient, while LoRa has better results. Using more than one type of communication at a time, all sent packets were received, while using one communication at a time, packet loss were perceived.
