IoT Platform with Distributed Brokerson MQTT

Abstract

Various wide-area Internet of Things services have been deployed. In most of these IoT services, a significant number of tiny data blocks are transferred across wide-area networks. Therefore, the transfer mechanisms should be simplified. One promising candidate for use as a transfer mechanism is MQ Telemetry Transport (MQTT). In this paper, an architecture for a distributed MQTT broker, referred to as a virtual ring approach, is proposed. This architecture complies with the IoT Data Exchange Platform, as discussed in ISO/IEC JTC 1/SC 41. The operations of this distributed broker architecture using a virtual ring network for real-time communication is also described, along with the superiority of the architecture based on a performance analysis using queuing models
