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. And then we propose a novel QoS-aware Real-Time Publish-Subscribe (QRTPS) service compatible to DDS for distributed real-time data acquisition. Furthermore, QRTPS is implemented on Agilor by using objects and RECA rules in Agilor. To illustrate the benefits of QRTPS for real-time data acquisition, an example application is presented. © 2009 Springer Berlin Heidelberg.
