Effect of Redundancy on Mean Time to Failure of Wireless Sensor Networks
In query-based wireless sensor networks (WSNs), the system must perform data sensing and retrieval and possibly aggregate data as a response at runtime. Since a WSN is often deplo...

Semantic Streams: A Framework for Composable Semantic Interpretation of Sensor Data
We present a framework called Semantic Streams that allows users to pose declarative queries over semantic interpretations of sensor data. For example, instead of querying raw magn...
