Middleware with QoS Support to Control Intelligent Systems

This paper presents the architecture of a middleware for control component-based distributed systems. The fundamental idea underlying this architecture is the use of a hierarchical communications structure called "logical namespace tree" and a structured set of control processes interconnected, called "logical sensors graph". This architecture is named Frame Sensor Adapter Control (FSA-Ctrl). The aim of FSA-Ctrl is to provide a simple interface to specify the control actions and ensure a communication with some specified QoS parameters restrictions. In this architecture both systems, communication and control, manages the QoS policies. The communication system is based on the Data Distribution Service (DDS), a standard proposed by Object Management Group (OMG). Control system is derived from the Sensor Web Enablement (SWE) model proposed by Open Geospatial Consortium (OGC). The system introduced in this paper is focused on the use of QoS parameters of the distributed systems components to manage the information redundancy.
