Actuation of an IoT Prototype System via MQTT for Smart Mobility

In this letter, we propose a simple MQTT-based IoT prototype system consisting only of open source and general-purpose electronic components. The Message Queueing Telemetry Transport (MQTT) protocol is attracting attention as a protocol for IoT. Although many results of data collection via MQTT have been reported, the actuation of IoT systems via MQTT has not been well reported. We demonstrate the actuation operation based on received messages and demonstrate the effectiveness of the proposed prototype system.
