DATA DISTRIBUTION SERVICE APPARATUS WITH VIRTUAL OBJECT ADAPTER FOR INTEROPERABILITY OF HETEROGENEOUS OBJECTS IN INTERNET OF THINGS (IoT) ENVIRONMENT

摘要

According to an embodiment of the present invention, a data distribution service (DDS) apparatus with a virtual object adapter for interworking heterogeneous objects in an internet of things (IoT) environment, in a DDS apparatus with a virtual object adapter based on a DDS for interworking heterogeneous objects in an IoT environment, comprises: a DDS entity managing unit for creating and managing a DDS entity by merging a plurality of DDS-based data topics received from at least one DDS node into one data topic; a topic managing unit for performing validation check and data filtering on the merged data topic; a user interface unit for monitoring data related to the merged data topic so as to model a virtual object desired by a user; and a virtual object instance management unit for generating and managing a virtual object instance by reflecting a quality of service (QoS) policy of the DDS on the modeled virtual object.;COPYRIGHT KIPO 2019
