<title>Sensor web: a new instrument concept</title>

Abstract

The confluence of the rapidly expanding sensor, computation, and telecommunication industries has allowed for a new instrument concept: the Sensor Web. A Sensor Web consists of intra-communicating, spatially-distributed sensor pods that are deployed to monitor and explore environments. It is capable of automated reasoning for it can perform intelligent autonomous operations in uncertain environments, respond to changing environmental conditions, and carry out automated diagnosis and recovery. Sensor Webs could have as much an impact on the uses of sensors as the Internet did on the uses of computers.Sensor Webs are often confused with "distributed sensors" or "sensor networks". The unique feature of the Sensor Web is that information gathered by one pod is shared and used by other pods. In contrast, sensor networks merely gather data and information gathered by a particular pod on such a network does not influence the behavior of another pod. Thus, sensor networks collect data while Sensor Webs can react and modify their behavior on the basis of the collected data. This paper will outline the potential of the Sensor Web concept and describe the Jet Propulsion Laboratory Sensor Webs Project (http://sensorwebs.jpl.nasa.gov/). In particular, a prototype Sensor Web deployed at the Huntington Botanical Gardens will be discussed.

Design and implementation of an archetype based interoperable knowledge eco-system for data buoys

“…Wireless sensor networks (WSNs) research, and more recently SensorWebs [13], have helped to contribute to the current fascination with the Internet of Things (IoT). The vision of an IoT, has precipitated an acceleration of development in sensor based data reporting techniques for ultra-constrained systems.…”

Design for Connecting Spatial Data Infrastructures With Sensor Web (Sensdi)

“…Hence a consistent set of encoding and interface standards as shown in Fig. 1 would have to be mandatorily developed for adapting and integrating sensor networks into an SDI application and OGC's Sensor Web Enablement (SWE) activity [26][27][28][29]. 2.2 Problems that will be addressed:…”

The Sensor Web: A Macro-Instrument for Coordinated Sensing

“…The first and second generation Sensor Webs produced are described in detail elsewhere [12]. Briefly, Sensor Web 1 demonstrated the viability of the concept in the laboratory, while Sensor Web 2 demonstrated the instrument in the field.…”
