Uma análise sobre as técnicas de Redes Tolerantes a Atrasos e Desconexões para mitigação de perda de informações na Internet das Coisas

Abstract

With the advent of the Internet of Things, new devices, which are part of our daily lives, are now connected to the Internet. The increasing use of sensors and equipments connected to the Internet is already our reality. These devices have limited energy, processing and memory, which demand for efficient solutions, but still compatible with the Internet. As a result, protocols were created to facilitate the communication of limited devices with the Internet, in order not to overload them. MQTT (Message Queue Telemetry Transport) is an example of a protocol aimed at devices with restrictions. However, due to their limited resources, these devices are often unable to always be connected, thus becoming challenging networks. To solve this problem, this work proposes an integration between the Delay Tolerant Networks (DTN) with the Internet of Things. In particular through the Bundle Protocol (BP) together with the MQTT protocol, as a mean to overcome these possible delays and disconnections in the Internet of Things.
