Trident is proposing the development of a Semantic Mesh of Intelligent Sensors, SMIS, an intelligent wireless sensor network for use in improving the performance of surveillance and security in crowded environments - such as airports, shopping districts, and sporting events. This network will be based around Trident's existing suite of wireless sensor nodes, which offer dynamic meshing capabilities along with very flexible sensor interfacing options and long battery runtimes. Trident proposes to enhance the capabilities of this sensor network by integrating sophisticated multi-modal signal and image processing capabilities for feature extraction, while maintaining low-power operation. The metadata produced by feature extraction processing will then be input to a semantic processing layer, which will utilize standard OWL-based ontological methods to infer threat activities. A wiki-based data store/interface will be used to provide a flexible methodology for interface to all sensor data, metadata, and semantic results, and will allow straightforward interfacing to other users and systems. The Phase I effort will consist of a detailed requirements analysis, followed by the development of an overall architecture, top-level development of component technology solutions, and proof-of-concept testing and demonstration of key capabilities.
