Distributed MQTT broker architecture using ring topology and its prototype

Some IoT services require simplified mechanisms in networks in order to communicate reliably and with low latency. This paper proposes a mechanism for connecting MQTT brokers for this purpose. In this proposal, the ring topology for connecting multiple brokers can efficiently process message routing and provide reliable and low latency communication. This paper describes the architecture and detailed operations of multiple ring-based brokers in MQTT. It also reports a prototype of the proposed system and its evaluation. Finally, the results demonstrate that this proposal is a promising and suitable approach.
