An Efficient Data Gathering and Notification System for Wireless Sensor Network with Geospatial Interoperability

With the rapidly growth of wireless sensor networks (WSN), the huge amount of raw data should be proceeded properly. We had proposed an innovated sensor observation service with web-based and GIS-based architecture, which is named WSN Application Service Platform (WASP). 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 an efficient data gathering and notification system for WSN with geospatial interoperability. Data with geo-coordinate can be preceded by the corresponding applications. For example, disaster report and alms distribution, etc. The proposed framework is helpful and efficient for users to enjoy the sensor observation service.
