Internet of Things, it is been more than a decade since this concept was introduced to the society. In this research we aim to compare three IoT application protocols; Advanced Messaging Queuing Protocol (AMQP), Message Queuing Telemetry Transport (MQTT) and Constrained Application Protocol (CoAP). The selected protocols efficiency will be evaluated using indicators related to Throughput and Round-Trip time (RTT). In the considered scenario an IoT device will transfer data to a server and waits for the response. The data will be sent in different sizes of packets. We have proposed a testbed using python programing language’s library SciPy and socket programming to evaluate the three protocols. 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.
