Ad-Hoc Query Processing Architecture

1. Ad-Hoc Query Processing Architecture Ross Rosemark

2. Goal • Design query processing architecture for sensor networks • Minimize energy consumption

3. Existing Query Processing Architectures • Fixed Query Processing Architectures • Infrastructure is built on entire network • Queries are submitted to infrastructure • Infrastructure processes query

4. Argue • This approach utilizes excessive energy • Deriving infrastructure • Performing metadata collection • Performing query execution • Performing result collection • Show that the problem with this approach is that the infrastructure is not designed to support a query in the network

5. Propose • Ad-Hoc query processing architecture • Build separate infrastructure that is designed to support each query in the sensor network • Protocol • Query submitted by user • Infrastructure built to support query

6. Problems • Ad-Hoc query processing architecture utilizes excessive energy deriving the infrastructure

7. Propose • Hybrid Query Processing Architecture • Mix between Ad-hoc and Fixed query processing architectures • Build only a partial infrastructure in an ad-hoc manner.. Some infrastructure is built in a fixed manner
