Ponte Message Broker Bridge Configuration Using MQTT and CoAP Protocol for Interoperability of IoT

Abstract

Internet of Things is emerging technology from few years where autonomous devices and technology communicate without human intervention. For IoT, many smart objects are interconnected and communicate through infrastructure of internet that is the base of a global network. The major challenge of IoT automation is to inter-connect heterogeneous devices, sensors and real-time application. Research has demonstrated recent development for a varied scope of solutions and devices of IoT eco-system. However, each interoperable technology provides its proprietary infrastructure and mechanism to communicate, which leads to IoT interoperability issue. Many research organizations, IoT industry and standardization institutes are working for empowering interoperability of resources between autonomous IoT devices. These efforts are categorized according to its implementation and usage considerations. The interoperable communication mechanism also depends on communication protocols and its communication models used at application layer. Major devices use MQTT, CoAP, RestAPI, AMQP and HTTP protocols at application layer for communication. This paper is intended to describe interoperability types and its impact on seamless communication. As a solution of interoperability issue, message bridge can be implemented between application layer protocols of request-response and publish-subscribe communication models. This paper demonstrate message bridge approach based on Ponte, which is open source IoT project designed by Eclipse for intercommunication between application layer protocols. The paper also demonstrates working of Ponte with the resolution of open issue related to message retention for cross protocol communication.

A Unified Method to Design Bridges for OPC UA PubSub Networks in the Industrial IoT

“…Second, the implementation of the PubSub bridge, presented in Section V-C, profits from some open-source libraries, including open62541 6 and Eclipse Mosquitto 7 . Since several implementations and libraries for the AMQP transport protocol are also available; thus, it is possible to reuse such tools to realize this conformance unit.…”

“…As in this research, Dave et al [6], [7] provide a concept of interoperability in the IoT and rely on it to classify the complexity of IoT systems. Our vision is different from theirs on two points.…”

Internet of Things Multi-protocol Interoperability with Syntactic Translation Capability

“…Ponte [9] is an Eclipse IoT project that provides open APIs to create applications that support the CoAP, HTTP, and MQTT communication protocols. Ponte provided a centralized solution to enable clients using different communication protocols to communicate easily with each other.…”

“…The proposed protocol translator can be deployed on either a cloud infrastructure or the IoT device itself. This framework depends on the IoT device description language [11] and was compared with Ponte www.ijacsa.thesai.org [9]. The results show that energy consumption is reduced in comparison with that of Ponte [9].…”

“…This framework depends on the IoT device description language [11] and was compared with Ponte www.ijacsa.thesai.org [9]. The results show that energy consumption is reduced in comparison with that of Ponte [9]. A disadvantage of this framework is that not all IoT devices can be part of this interoperable ecosystem: the device should have an Internet connection (e.g., Ethernet, cellular network, or Wi-Fi) and an operating system that supports multithreading to integrate with this ecosystem.…”
