1. A Few Words About Me Background: Sensor Database Systems –Cougar@Cornell Bluetooth and Sensor Networks –Manatee @ University of Copenhagen Interests: Sensor network applications –Hogthrob Project (2004/07) Bridging the gap between RFID and Backend Infrastructure –Collaboration with Tagvision (2005/-) Teaching –Teachware –Remote Programming Platform Relations with Industry –Collaboration with Freescale –Danish University/ Industry Network

2. Hogthrob The real HOGTHROB Goals: Functionalities –Tracking –Detecting Heat Period –… Low Cost (~1 €) Low Energy (2 years) Developing a Sensor Network Infrastructure for Sow Monitoring

3. Application Detection Model –Adaptation to individual sows –Dictates sensor modality Accelerometer 2D, 3D –Dictates duty cycling Sensor Network Infrastructure –Alert at home + info inside the penn (mobile Phone) –Star topology –Wake-up: in-channel, add-on low power radio Sensor Node Design –Packaging –Energy source Battery, harvesting Dictates energy budget –Generic node vs. Custom Design –SW design on given HW platform vs. Co-design COTS vs. custom components Goals: Functionalities –Tracking –Detecting Heat Period Low Cost (~1 €) Low Energy (2 years)

4. How to Explore the Design Space? Flexible Platform (Hogthrob V0) –Pluggable sensorboard/radioboard –FPGA-based Various micro-controller designs Hardware accelerators Embedded Simulation –Trace collected by instruction snooping Power Model (time priced automata) Power Profile (synthesis tools simulation, measurements) –Actual stimuli

5. Beyond Pigs Sensor Networks developments driven by –Automotive, logistics and business intelligence, production automation, health and well being, entertainment, environment industries –Regulatory constraints: food safety, homeland security Cost and energy efficiency are key –Lessons to learn from Nokia
