QoS-Aware Publish-Subscribe Service for Real-Time Data Acquisition

Abstract: Many complex distributed real-time applications need complicated processing and sharing of an extensive amount of data under critical timing constraints. In this paper, we present a comprehensive overview of the Data Distribution Service standard (DDS) and describe its QoS features for developing real-time applications. An overview of an active real-time database (ARTDB) named Agilor is also provided. For efficient expressing QoS policy in Agilor, a Real-time ECA (RECA) rule model is presented based on common ECA rule.
