Comparison of IoT protocols performance

Internet of Things, it is been more than a decade since this concept was introduced to the society. In this research we have compared three IoT application protocols; Advanced Messaging Queuing Protocol (AMQP), Message Queuing Telemetry Transport (MQTT) and Constrained Application Protocol (CoAP). We have proposed a testbed using python programing language's library SciPy and socket programming to evaluate the three protocols. The selected protocols efficiency were evaluated using indicators related to Throughput and Round-Trip time (RTT). In the considered scenario an IoT device sends data to the server and waits for the response. The packets were sent in different sizes. The generated data were collected and saved in CSV files using Pandas library. Moreover, Anaconda was used to analayze and visualize the data. Experimentation tests reveal which protocol is best suited for different scenarios accordingly. Results show that overall MQTT achieves the highest protocols efficiency among other protocols.
