RESOURCES

Power Consumption at 1 MHz, 1.8V, 25°C Active: 0.4 mA Power-down Mode: 0.1 μA Power-save Mode: 0.7 μA

XBee Series 2 TX Current: 40 mA (@3.3 V) RX Current: 40 mA (@3.3 V) Power-down Current: < 1 μA @ 25oC

40mA = ~ 1.5 day#(lipo battery 1700mAh)

Domain Specific Language!+ Code Generation

Functional Loop Fusion

Grouped Communication

Today!! 3 nodes (ATMEGA1284p + XBee)!! +!manual heartbeat implementation!!

Tomorrow!! + manual reputation implementation!!

Soon!! + (manually) generated fused code!! = evaluation ROM/RAM, processing and ! ! !! ! network usage!!

Near Future!! + port to AVR RAVEN!! + deployable implementation
