MQTT- CoAP Interconnector: IoT Interoperability Solution for Application Layer Protocols

Internet of Things (IoT) is a developing technology from recent decades which works on heterogeneous machines and technology interoperate without human involvement. The challenge of IoT automation is to coordinate autonomous devices, sensors and real-time applications for seamless communication. Many organizations and researchers have demonstrated various solutions for a wide range of IoT devices. However, the available system provides its specific IoT infrastructure, devices, APIs and data formats, which leads to interoperability issues. A new data interoperability solution MQTT-CoAP Interconnector (MCI) is designed for interoperability of MQTT and CoAP protocols at the application layer of IoT. It works as a bridge between the local message of MQTT and remote message of CoAP with data parsing capacity. MCIis the lightweight interoperability solution designed with consideration of resource-constrained devices of the IoT ecosystem. As compared to available open-source solutions, MCI performs better considering communication parameters like transmission time, throughput, latency and packet loss. Thus, the MCI interoperability solution can benefit to resolve one of the major issues of the IoT ecosystem.
