FUOTA-IOT: uma proposta de aprimoramento do padrão DLMS para atualização de firmware em dispositivos de internet das coisas

Abstract

The Internet of Things (IOT) has prospered a lot in the last decade, which has led to the significant emergence of new solutions and, as a result, millions of new devices have been installed. With the prospect of even greater growth, some concerns arise related to the safety and maintenance of these devices, what is desirable is that good software engineering practices be incorporated into the development and maintenance process of these new solutions where continuous development is intended. For updates to be delivered to these devices, whether corrections of bugs or new features, the firmware update process is necessary. Due to the characteristics of these devices, the most used update process is Firmware Update Over the Air - FUOTA, which allows using wireless communication technologies for remote updating. This work aims to sketch, program and validate an efficient transmission model from firmware to IoT devices that allows independence of communication technology, which can be adopted as a standard for any IoT solution. due to settings that optimize data consumption, transmission time and success rate in the process. The work also aims to present the main fundamentals of IoT, Wireless Sensor Networks, DLMS and the challenges involved in the update process. In the course of this work, it will be possible to conclude that it is possible to determine a standardization in the firmware update process without underusing the selected communication technology, an important contribution to the process of developing new solutions that allows a reduction in development time in addition to reduction of device development and maintenance costs.
