In general, CoEs assist in two forms to increase interoperability among IEEE standards:

• Assist in ensuring interoperability inside standards’ families
• Provide a concrete model for interoperability testing of different conformant products implementing the same standard (plug-fest)

Additionally, any CoE can provide additional services regarding interoperability among different standards, systems, and applications in terms of protocols, communications, and other connectivity services.

CoE@KEIO

The CoE@JP offers the validation of smart transducers operating over MQTT/MQTTv5 as an experimental setup compatible with the following standards:

• IEEE P21451-1-6 - Standard for a Smart Transducer Interface for Sensors, Actuators, and Devices - Message Queue Telemetry Transport (MQTT) for Networked Device Communication
• IEEE P2805 - P2805.1 - Self-Management Protocols for Edge Computing Node, P2805.2 - Data acquisition, Filtering and buffering Protocols for Edge Computing Node, and P2805.3 - Cloud-Edge Collaboration Protocols for Machine Learning mainly focusing on the implantation of protocols using MQTT.
• IEEE P2668 - Standard for Maturity Index of Internet-of-things: Evaluation, Grading, and Ranking
• IEEE 1451.0 – Information technology — Smart transducer interface for sensors and actuators — Common functions, communication protocols, and Transducer Electronic Data Sheet (TEDS) formats
• IEEE 1451.1 – Information technology — Smart transducer interface for sensors and actuators — Part 1: Network Capable Application Processor (NCAP) information model
