DDS System for interoperation network of IoT and network of Zigbee based DDS and Method thereof

摘要

The present invention relates to a system and method for interworking between a DDS-based Internet and a ZigBee network, wherein different applications can exchange information through topic connection to manage distributed data based on a publication / A Data Distributed Service (DDS) system that provides an interface to allow the user to interact with the system; Events or services from ZigBee nodes in the ZigBee network and converts them into data topics, event topics or service topics and publishes them to the DDS system, subscribes data topics, event topics or service topics from the DDS system, And a ZigBee adapter that allocates a virtual ZigBee node for providing to the network and provides interoperation between different networks of the object Internet environment. Accordingly, the present invention provides a ZigBee-based ZigBee packet data / event / service in the Internet environment using a ZigBee adapter, a data / event / service in a ZigBee network as a DDS-based topic, Based on DDS, it provides interoperability between ZigBee network and other networks in the Internet environment, thereby enabling bidirectional communication and data / event / service interworking between different networks. Through the quality of service (QoS) supported by DDS Real-time and reliability of interoperability can be assured.
