MQTT Protocol Use Cases in the Internet of Things

In the imminent generations, the Internet of Things (IoT) will have a vital role in ‘Networking’. There are a lot of subscribing/publish protocols used in IoT like MQTT, AMQP, XMPP, HTTP etc., but every protocol used here will not have the same features required for the Internet of Things. This paper helps you to find which is the best and efficient protocol through the use cases and the Big Data analysis used in IoT. To choose the best protocol, it should be used in the real-world application and analyzed through some statistical measurements, as like in this study two use cases are taken to experiment with the protocol. Light-weight MQTT (Message queuing telemetry transport) protocol is vastly used in IoT, So MQTT protocol is used to subscribe/publish in these use cases, using the use cases measurements (speed of the transmission of messages and throughput of the message transmission) are measured and the security systems are either explained. Mainly for the use cases like home automation and vehicular network, there are a huge number of resources like sensors are used, these sensors collect massive data, so for storing these massive data big data is used. This paper majorly focuses on the use cases of MQTT protocol in IoT, the advantages of using MQTT protocol and big data analytics used in IoT.
