Sensor ASIAPromote Sensor Observation in ASIA using Sensor Service GRID(SSG) as an infrastructureSensor Plug & PlayEasy Installation/Archive/Publishing for scientist/engineer/anyoneOff-the-shelf Sensor-node, SensorUbiquitous Open Sensor NetworkHigh-density ( Spatial/temporal ) observationsEnvironmentAgricultureMeteorologyEducationSecurity.Interface to MetBroker/Digital Asia/Digital EarthApplication testbed of SSG - ALFAEThailand, Malaysia, Japan.Contribution to BusinessEasy installation will reduce cost, increase sensors/FS nodeVarious program to obtain/share data

SOS: Sensor Observation ServiceOGC: Open Geo-Spatial Consortium Standards on SWESOS ( Sensor Observation Service )SPS ( Sensor Planning Service )WNS ( Web Notification Service )Obtain Sensor InformationStandard Query and AnswerO&M Documents ( xml )Sensor Name, Location, Spec, Data..Provide standard interface to sensor dataLimitationsNot field orientedGap to physical sensor setupSensor configurationSecurityPublic Service

We propose SSG; Sensor Service GRIDProvide useful service layer on top of SOSPush SOS ( OGC Sensor Observation Service ) to sensor side as much as possible: on Field ServerSensor Plug & Play Automatic ConfigurationA/D; Sensor output -> Measurement DataData Path ( Sensor Node->Server ->Archiving/Publishing )VisualizationSecurityHigh Adaptability in various Network/Power/Regulation EnvironmentGeographic Information Web ServiceGateway to Metbroker -> Seamless connection to/from existing DB
