There is a significant challenge in designing, optimizing, deploying and managing complex sensor networks over heterogeneous communications infrastructures. The ITA Sensor Fabric addresses these challenges in the areas of sensor identification and discovery, sensor access and control, and sensor data consumability, by extending the message bus model commonly found in commercial IT infrastructures out to the edge of the network. In this paper we take the message bus model further into a semantically rich, model-based design and analysis approach that considers the sensor network and its contained services as a Service Oriented Architecture. We present an application of a hierarchic schema for nested service definitions together with an initial ontology that describes the assets and services deployed in a sensor network infrastructure.
This study discusses a 10-year effort by Standards Committee 37 of the International Organisation for Standardisation/ International Electrotechnical Commission Joint Technical Committee 1 (ISO/IEC JTC1 SC37) to create a systematic vocabulary for the field of 'biometrics' based on international standards for vocabulary development. That process has now produced a new International Standard (ISO/IEC 2382-37:2012), which conceptualises and defines 121 terms that are most central to the proposed field. This study will review some of the philosophical and operational principles of vocabulary development within SC37, present 11 of the most commonly used standardised terms with their definitions and discuss some of the conceptual changes implicit in the new vocabulary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
