Análise dos protocolos HTTP e MQTT para projetos IOT utilizando internet fibra óptica e internet móvel

Abstract

With the constant evolution of technology, there is an increasing number of devices connected to the internet, which characterizes the term Internet of Things. Thinking about the evolution of technology, needs and challenges of each project, the developer has to adapt the IoT architecture so that the operation and communication with the server is the best possible, free of errors and problems to achieve the proposed goal. The person responsible needs to know which is the best way to communicate with the server and to have knowledge about the protocols that will be used. This work analyzes the data flow with the HTTP (Hypertext Transfer Protocol) and MQTT (Message Queuing Telemetry Transport) protocols with different means of communication (Fiber Internet, 3G and 4G mobile Internet), through an Internet of Things project, which sends data of temperature and relative humidity of the air to a cloud server and thus perform an analysis between the protocols and means of communication with the results obtained. The results show that the MQTT protocol requires less bandwidth and the means of communication (Fiber, 3G and 4G mobile Internet) meet the bandwidth needs of the project.
