Environmental sensors have continuously improved by becoming smaller, cheaper, and more intelligent over the past years. As consequence of these technological advancements, sensors are increasingly deployed to monitor our environment. The large variety of available sensor types with often incompatible protocols complicates the integration of sensors into(More)
An ever-increasing number of sensor resources are being exposed via the World Wide Web. Discovery, selection and use of these sensors and their observations require a robust sensor information model, but the homogenous description of sensor metadata is a complex and difficult task. Currently, the only available robust model is SensorML, which is(More)
With myriads sensors out there, the manual matching of their characteristics and constraints is not feasible anymore and requires a detailed understanding of sensor metadata and observed properties. Thus, Plug & Play like approaches that ease the matching of sensors to Web services have become popular in Sensor Web Enablement research. Simple matching,(More)
This work1 enables an automated integration of sensors and services on the Sensor Web. The Sensor Web is defined as an infrastructure which enables the interoperable usage of sensor resources by providing services for (1) discovery, (2) access, (3) tasking, as well as (4) eventing & alerting [2]. The notion of the Sensor Web has been largely influenced by(More)
