Converging MQTT resources in ETSI standards based M2M platform

Abstract

One of the key challenges of the Internet of Things (IoT) is the integration of heterogeneous technologies and communications solutions. This paper proposes a method to integrate Message Queuing Telemetry Transport (MQTT) protocol with the ETSI M2M architecture via a new network function called MQTT proxy. The MQTT proxy, on the one side, acts as an MQTT broker to the MQTT clients. While on the other side, it serves as a Gateway Application (GA) for interfacing with the ETSI M2M-compliant architecture, specifically OpenMTC developed by Fraunhofer FOKUS. By the MQTT Proxy, MQTT resources can be converged in the ETSI M2M architecture. Finally, we compare the MQTT Proxy with our previous HTTP Proxy.
