MQTT-Topics Management System for sharing of Open Data

At present, the sharing of open data in any city is importance. The shared data, e.g., flood monitoring data, earthquake data, or traffic data, can be used to improve the way of human life. MQTT, the lightweight messaging protocol based on the publish-subscribe concept, is the most popular protocols used to share these data. There are two elements of MQTT messaging for sharing of any data; topic and message. The first one is used to define which the subscriber are received which data and the data that we need to share are presented in the message element. To share the data with MQTT protocol, MQTT-Topic Naming Criteria of Open Data for Smart Cities (MTNC) was proposed in our previous work. In this paper, we propose MQTT-Topics Management System (MTMS) to manage the topics of the MQTT messages shared by any publisher based on MTNC. The experimental result shows that the proposed system get the high average score of usability, design and the benefits.
