Many sensor networks have been deployed to monitor Earth’s environment, and more will follow in the future. Environmental sensors have improved continuously by becoming smaller, cheaper, and more intelligent. Due to the large number of sensor manufacturers and differing accompanying protocols, integrating diverse sensors into observation systems is not straightforward. A coherent infrastructure is needed to treat sensors in an interoperable, platform-independent and uniform way. The concept of the Sensor Web reflects such a kind of infrastructure for sharing, finding, and accessing sensors and their data across different applications. It hides the heterogeneous sensor hardware and communication protocols from the applications built on top of it. The Sensor Web Enablement initiative of the Open Geospatial Consortium standardizes web service interfaces and data encodings which can be used as building blocks for a Sensor Web. This article illustrates and analyzes the recent developments of the new generation of the Sensor Web Enablement specification framework. Further, we relate the Sensor Web to other emerging concepts such as the Web of Things and point out challenges and resulting future work topics for research on Sensor Web Enablement.

Current fire detection systems sense a fire by responding to the by-products or symptoms of fire like heat, smoke and light radiation. Our aim is to increase the reliability of fire alarms and to eliminate nuisance alarms. A quick incident assessment by continuous tracking of the fire spread and knowledge about the incident location enables the decision making about the fire fighting strategy and adequate resource strategy and resource mitigation planning. In this paper we show an approach how to apply the emerging Sensor Web Enablement technology to this use case for implementing an improved fire detection system in a very efficient manner. A comprehensive description of the architecture of Sensor Web Enablement is given in order to explain how the system is built. 1628 Close Next 1630 Next Prev First Next Prev First
