Rundensteiner 1 One Stream Per Sensor Device VRML Modeling of the Test Arena Sensor Reading (along with Alarm Levels) Alarm Goal L 3 Analyze measurements from large numbers of sensor-streams. Detector Block L 2 L 1 Integrate declarative queries with sensor clustering. Exploit spatial proximity to reason about spread. Control associated data acquisition rates at run-time. Thermocouple Tree Sensors Streams Query Evaluation – Over 100’s of Sensors. Fire. Stream Architecture High-ARY Join Operator Data Stream Manager Fire Monitoring Queries Ambient Condition Evaluation Determination of environment conditions over time by flexible aggregation of streams and sensor meta data. Sensor Event Detection Identification of a fire or smoke event to trigger more computationally intensive tracking queries. Monitor Fire Spread Data Acquisition Controller Fire Event Detection Spatial Query Evaluation Spatial Store Stream Matching Logic Fire Monitoring Engine Cluster Query Evaluation Sensor Meta-data Query Execution Engine Computation of smoke/heat clusters composed of sensors to monitor movement of fire. Stream Query Logic Fire Models Query Translator Graphical User Interface Fire Prediction Result Prediction of Live Fire User Query Fire. Stream User Interface Live Fire Reduce participants in join processing by exploiting sensor clustering based on meta data. Stream Matching Logic Simulations Compute relative distances among sensors (direct path) by spatial query support, such as nearest-neighbor, spatial-overlap etc. Cluster Movement Flaming Fire Smoldering Fire Application of data mining techniques by pattern matching of simulated fire streams against the live fire stream. 1 Computer Note: Bibliography of the diagrams with their sources are listed in the handout Science Department, 2 Fire Protection Engineering Department Database Systems Research Group (DSRG) @ WPI
