A Flexible SWE-based Data Observation and Event Notification Framework

Wireless sensor network (WSN) is growing rapidly in recent years. The sensed raw data are usually hard to be understood by users. We had proposed an innovated sensor observation service with web-based and GIS-based architecture, which is named WSN Application Service Platform (WASP)[7]. WASP is a data management center, which designed with the concept of Services Oriented Application (SOA) as a Cloud Service. The raw data can be transferred into add-on valued data and shown on the web pages through WASP. Users can query and obtain the valuable information and realize the meanings of these data through web-based interfaces, which is defined in Sensor Web Enablement (SWE) by Open Geospatial Consortium (OGC). Based on WASP, we propose a flexible SWE-based data gathering and notification system on Social Networks for wireless sensor networks. Data can be shown immediately on social networks. Moreover, all sensors and devices provide their location information to data center and form a community. The proposed system provides remote control functions for WSN to increase the data retrieval efficiency based on OGC SWE Sensor Observation Service (SOS), Sensor Planning Service (SPS), and Sensor Alert Service (SAS).
