Ad-Hoc Query Processing Architecture

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
