“…The user who requests the targeted observation should be notified of its status by messages. Traffic congestion pricing is one of the applications that use the measurements returned from traffic sensors [31]. The message of congestion status should be broadcast to relevant toll stations for pricing the toll accordingly.…”

The Sensor Web connects live sensors and Earth Science models (ESM). A workflow is one approach for designing, implementing, and constructing a live link between sensors and ESM. The Sensor Web consists of many individual Web services. A workflow coordinates them to enable bi-directional connectivity between sensors and ESMs. This study uses Business Process Execution Language as the base scripting language to design, author, deploy, and execute workflows. Message-level coordination mechanisms are developed, implemented, and demonstrated in two scenarios-bird migratory modeling and georeferenceable imagery workflow. The advantage of message-level coordination is shortcutting the data flow.Index Terms-Sensor web, workflow, event driven system, earth science model, web service.

Wireless Sensor Networks (WSN) consist of thousands of spatially distributed, low cost, low energy, unattended, and resource constrained sensor nodes for environmental monitoring, pollution detections, battle field surveillance etc. A Sensor Web (SW) is a web-based WSN, where a web application works as a gateway between the WSN and Internet. The Web interface is connected to the World Wide Web or huge computing resources and integrates sensor data and networks. Two major SW architectures are Open Geospatial Consortium defined Sensor Web Enablement (SWE) and Microsoft defined SenseMap. On the other hand, SW is used in academic purposes, agriculture, traffic monitoring, disasters monitoring, and smart home etc. There are many other novel applications as well as middleware for SW. Moreover, researchers from different fields give emphasis on different aspects of SW, while combining these two networks: sensor and web. They focus on strategies and technical issues of SW as well the utilization of sensor data by distributing it through the Web. In this paper, we discuss and compare existing SW architectures. We also present several SW applications and classify them with some potential research issues in this field.

“…Examples of other uses of STK for UAV systems in real-time operations and post-mission analysis can be found online at http://www.agi.com/solutions/specializedAreas/uav/. Some complementary work in building Earth Observing simulators for meteorology is also underway (Higgins et al, 2005;Kalb et al, 2005;Halem et al, 2007;Seablom et al, 2007). The end product of these studies will be a "sensor web simulator" (SWS) that would objectively quantify the scientific return of a fully functional model-driven meteorological sensor web.…”
