Protocol-Based Testing for Unmanned Gasoline Level Monitoring System

An unmanned monitoring system is proposed in order to ensure the remaining volume of fluid inside a tank. Internet of Things (IoT) concept is used when developing such system. IoT device has been known able to support faster and more efficient procedure in any automatic monitoring. Arduino-based microcontroller is implemented as the main IoT component. In order to communicate within the network system, the proposed IoT uses a data transfer protocol. This paper presents a comparison between Message Queuing Telemetry Transport (MQTT) protocol and Hyper-Text Transfer Protocol (HTTP). The comparison is based on the Quality of Service (QoS) parameters that are captures during data transmission from the IoT device to the server using certain standards for both protocols. Data transmission and retrieval shall not be affected by the environment, be free from error and the data is not broken or lost. Delay, Throughput, Packet Loss, and Packet Delivery are the QoS parameters used in the testing. The experiment was conducted for 6 days. Based on the results comparison, it can be concluded that the perfomance of MQTT protocol is far better than HTTP for each parameters. That is the reason why MQTT is more suitable to support Arduino-based IoT device to monitor fluid volume.
