2. Exploiting Semantics for Event Detection Systems
State A
State B
State D
State C
Goals and Motivation
A robust and scalable middleware technology that can handle challenges related to:
The need for rapid deployment (e.g., self calibration).
Limited resources (e.g., network bandwidth).
Heterogeneity of sensors.
1. Rapid Deployment – Learn A State Transition Model
2. Limited Resources – Learn Sensor Association Model
Approach
Preliminary Results
Model the normal operation of a sensor.
Exploit it for rapid deployment.
Model the associations between data generating sensors.
Exploit it for resource allocation.
More Reliable Event Detection
Better Recall of Events
