Análise Experimental do Impacto da Transmissão de Dados via Wifi na Eficiência Energética de Dispositivos IoT

Recently, the Internet of Things (IoT) emerged to evolve tasks and services in daily activities of the society, demanding more robust wireless transmissions, such as IEEE 802.11/WiFi. However, there is still no study about the impact of this technology on the battery life of IoT devices, considering the size of the transmitted packets and the Maximum Transmission Unit (MTU) defined. Within this context, this paper presents an experimental analysis of the impact of data transmission through IEEE 802.11/WiFi on the energy efficiency of IoT devices. Experiments were carried out in a testbed composed of ESP8266X/WEMOS devices, showing that both the packet size and the defined MTU influence the energy consumption of the devices.
