“Sensor Observation Service (SOS) in Sensor Web Enablement (SWE) proposed by Open Geospatial Consortium (OGC) collects sensing data through Asset Manger. The data is transformed into Observation & Measurement (O&M) and it is transferred to the client. SOS, dependent on the Asset Manager, needs to be synchronized every time the change occurs to the Asset Manager. Also, the expansion of Sensor Web often causes load concentration. In this paper, we propose new SWE architecture integrating various SOS to control the vendor and the schema of the DBMS. This architecture can minimize modification of SOS due to the change of sensor type. Also, the new component of SWE can manage the load of requests.”
