• Application: Light/Temperature Application: Light/Temperature SensingSensing

• Language = NesCLanguage = NesC

• Testing: TOSSIMTesting: TOSSIM

• GUI: TinyViz, GraphVizGUI: TinyViz, GraphViz

ImplementationImplementation• Sensor nodes and 1 Base StationSensor nodes and 1 Base Station

• Sensor nodeSensor node– periodically takes light readings and sends a periodically takes light readings and sends a

group of readings over radio to base stationgroup of readings over radio to base station

• Base StationBase Station– Forwards packets through serial port to PCForwards packets through serial port to PC

• Led Module used Led Module used – yellow LED is toggled when new packet sentyellow LED is toggled when new packet sent– red LED is on when the light sensor reading is red LED is on when the light sensor reading is

above some constant value (0x0300 or 768)above some constant value (0x0300 or 768)

Routing SchemeRouting Scheme• Base Station simply broadcasts a beacon packet. Base Station simply broadcasts a beacon packet. • Those who hear itThose who hear it

– Set one hop neighbor as base station.Set one hop neighbor as base station.– Broadcast beacon packet.Broadcast beacon packet.
