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 PerCom 2009 Work in Progress – One Minute Madness
