Proposta e desenvolvimento de um sistema de gerência de dispositivos de rede restritos baseados em LoRaWAN e LwM2M

Abstract

This work proposes a communication management system for restricted devices. Several features have been developed that can be used on different devices that have limited resources, as is typically used in IoT. The created solution was used in the context of Low Power Wide Area Network (LPWAN) networks, characterized by having a long range, low energy consumption and data rate limitations. LoRa is one of the main technologies in this category. That is why it was used here as a reference for use. The proposed management system uses the Lightweight Machine to Machine (LwM2M) protocol as an information flow standard. It defines a communication and data model between clients (devices) and servers, both for network management operations and for supporting data traffic between applications and devices. The presented solution is validated in a scenario with LoRa devices that use the LoRaWAN protocol. The main functionalities suggested were implemented and tested in different scenarios, to illustrate the effectiveness of the proposal in the context of restricted networks. The results show that the developed system allows the execution of the main management operations following an LwM2M standard, as well as providing a series of information that assist in interventions on the network and contribute to its correct functioning. The created system can be used in different applications within the context of IoT and in different communication technologies.
