Detailed explanation-1: -In MQTT, the IoT devices are interconnected via the broker, meaning that there is no direct connection between clients and the broker relays the messages between clients. Unlike most communication protocols, this message relay is not restricted to a one-to-one model.
Detailed explanation-2: -According to measurements in 3G networks, throughput of MQTT is 93 times faster than HTTP’s. Besides, in comparison to HTTP, MQTT Protocol ensures high delivery guarantees. There are 3 levels of Quality of Services:-at most once: guarantees a best effort delivery.
Detailed explanation-3: -Depending on the CPU capabilities, MQTT can connect many thousands or even millions of devices. Besides the scalability, it is simple to use. It has low system requirements and high compatibility with Internet-connected applications. That is why this network technology is so popular in the IoT.
