説明

This paper proposes Gamma, which is a new distributed MQTT system, to improve the usefulness of distributed MQTT systems for sharing spatial data. In the experiment, it has been found that Gamma can process more messages than a single MQTT broker. It is confirmed that Gamma achieves scalability by increasing the number of Gateways and distributed MQTT brokers. Furthermore, it is confirmed that the efficiency of the distributed MQTT system can be improved by setting the responsibility area of Gateways.
