A new routing mechanism based on layer 2 control in MQTT networks with multiple brokers

抄録

In MQTT for IoT communication, multiple brokers should be deployed to accommodate a number of end devices. However, routing mechanisms among these brokers have yet to be specified. In this paper, a new routing mechanism for this purpose is proposed. This mechanism is aimed at layer 2 base control. It provides co-operations with MQTT and the Spanning Tree Protocol and invokes a traffic reduction and simplified transfer by an independent IP flow. In this paper, the detailed communication sequences are proposed, and the reasonability of the proposed mechanism based on a performance evaluation using prototyping is highlighted.
