Uma estratégia de wake-up radio para comunicação orientada a eventos em uma rede lorawan classe A

Abstract

This paper aims to develop a strategy based on Wake-Up Radio technology for event-driven communication in a Class A LoRaWAN network. For this, radio wake-up circuits were developed, as well as embedded software algorithms for microcontrolled platforms, with the objective of reducing the energy consumption of an end-node of a Class A LoRaWAN network. Initially, a survey was conducted on microcontrolled platforms that could be used for the development of a LoRaWAN class A network. Next, surveys of techno-scientific materials related to Wake-Up Radio in LoRaWAN networks were performed. This required research on low-power radios, to be used as secondary radios for the devices belonging to the network. Finally, communications between the devices were established so that the project could be validated and the device consumption measured.
