Abstract

The number of applications based on the Message Queuing Telemetry Transport (MQTT) protocol has increased greatly, making it the world's most popular pub/sub protocol. This paper presents the development and evaluation of an MQTT adaptor for the InterSCity platform, an integrated open-source software for the development of robust smart cities and Internet of Things applications. The adaptor allows sensors and actuators to publish data to and receive commands from InterSCity using the MQTT protocol. Performance evaluation has shown that using the MQTT adaptor could be more efficient than using the standard HTTP API. For example, with the use of MQTT, the observed throughput was up to 84.27 times higher than with the use of HTTP.
