An Implementation of Efficient Data Gathering and Notification Systems with Geospatial Interoperability

This paper is about the development of Efficient Data Gathering and Notification System for Wireless Sensor Network with Geospatial Interoperability. Designing a flexible Sensor Web Enablement (SWE) based Data Observation and Event Notification Framework on Social Networks. With the rapidly growth of wireless sensor networks (WSN), more and more services provide people up-to-date information such as weather forecast, earthquake reports, fire alarm, even for the surveillance system, and so on. The 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 SWE by Open Geospatial Consortium (OGC). Based on WASP, we propose a flexible SWE-based Data Observation and Event Notification Framework on Social Networks for smart home applications. Data can be shown immediately on social networks (i.e. Facebook) via the framework. All sensors and devices provide their location information to data center and form a community. The proposed framework 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). The proposed system is helpful and efficient for user to enjoy the smart home applications with geospatial information.
