Análise e implementação do suporte ao transporte de pacotes IPv6/UDP em redes LoRaWAN utilizando o protocolo de comunicação SCHC aplicado a leitores inteligentes de energia elétrica

Abstract

With the constant growth of devices related to the Internet of Things, it is necessary to implement solutions that make possible efficient and robust communications between end devices and the applications that may establish a connection with them. In this scenario, the implementation of LPWANs is constantly advancing, although these technologies do not natively support IP addressing due to their technical limitations. As a result, these devices cannot be directly accessed via established and widely used Internet standards. This work aimed to implement an adaptive layer to meet this need, considering its application in a complete environment, in which the final purpose is the communication with a smart meter. For this, the SCHC protocol was implemented to enable direct communication between a LoRaWAN network and the Internet through IPv6/UDP packets. In addition to establishing remote communication with the meter from an application responsible for sending and receiving DLMS/COSEM packets, this project also presents an analysis of the SCHC protocol operating in a LoRaWAN network, in order to to evaluate the algorithms implementations and their performance, considering a complete communication network. Finally, possible improvements are presented in order to enable better results accompanied by the continuation of the work.
