XMDR-DAI-based USN multimedia MetaData management agent for sensor networks

In a ubiquitous sensor network (USN) environment, it is necessary to define and manage a single metadata between the multimedia sensor and multimedia sensor node for interoperability purposes. One method to resolve this issue is the SensorML (Sensor Model Language), which is standard language that can be applied to sensor modeling. SensorML describes the model for data processing between multimedia sensors and provides a framework that can describe the information of each sensor. In this paper, an XMDR-DAI-based USN multimedia metadata is defined to describe the application of sensor devices, sensor nodes and sensor network information. And then an agent technology is used for effective storing and search of XMDR-DAI-based USN multimedia metadata. Sensor multimedia metadata can maintain interoperability in a USN multimedia environment based on SensorML, and the metadata management system can be directly used for metadata management in USN multimedia middleware or applications.
