Data Consumption Pattern of MQTT Protocol for IoT Applications

Abstract

In connecting the networks and people, the HTTP Protocol played a greater role and it is the most widely used protocol for data transfer in variety of applications. In IoT, we got to establish connections between “machines and things”. Their communication requirements were different from current needs of Internet and associated data communications. So, HTTP protocol looks quite heavy for Internet of Things (IoT) applications, due to the overheads of HTTP. Hence, we analysed the data consumption pattern of a light weight protocol Message Queue Telemetry Transport (MQTT) supported by literature study and practical validation using Orange-Pi controlled test bed. The test bed comprises PIR Motion sensor coupled with WeMos microcontroller that sends input to the Orange-Pi Gateway over MQTT Protocol. Along with the test results, this paper summarizes the benefits of using MQTT Protocol, in IoT Applications.
