Comparison of MQTT & COAP Application Layer Protocols of IoT
The Internet of Things (IoT) is the network of physical objects, devices, vehicles, buildings and other items which are embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data. In this paper we compare the performance of two application layer protocols, that are Constrained Application Protocol (CoAP) and Message Queuing Telemetry Transport (MQTT)in an Internet of Things (IoT) scenario. The two protocols have been implemented on the same low cost and low complexity software platform, suitable for IoT applications. The performance, in terms of protocol architecture, Transport layer, Framebytes, Headersize, Payload etc. strictly related experimentally evaluated. Keywords - Internet of Things (IoT), MQTT, CoAP, Wireshark.
