Exploit Non-Uniformities I: Tiered Architecture
We are implementing a sensor net hierarchy: PC-104s, tags, motes, ephemeral one-shot sensors
Save energy by
- Running the lower power and more numerous nodes at higher duty cycles than larger ones
- Having low-power “pre-processors” activate higher power nodes or components (Sensoria approach)
Components within a node can be tiered too
- Our “tags” are a stack of loosely coupled boards
- Interrupts active high-energy assets only on demand
