  1. SoNDa Sensor Network for Data Politehnica University of Bucharest

  2. SoNDa Architecture

  3. Sensor Motes

  4. AVR Raven • Development kit for wireless 802.15.4, 6LoWPAN siZigbee. • AVRRAVEN • 2 Pico Power uC • 2.4GHz Transceiver • LCD, joystick, microphone • AVRRZUSBSTICK • Gateway node -> PC connection • USB port

  5. Sensor Node Architecture • Wireless sensor node (mote) • Runs Contiki OS and registers into an IPv6 ad-hoc wireless network • Multiple sensor slots • Energy harvesting module

  6. Wireless Power Metering • Specialized sensor node • Measures energy consumption from the 220VAC power grid • Measured parameters: • Voltage • Current • Active power • Runs alongside the other existing sensor nodes

  7. Sensors • Temperature • Light Intensity • Humidity • Acceleration • Atmospheric Pressure • CO2 Gas • Methane Gas • Diesel and Gasoline Exhaust

  8. Application Scenarios • Temperature → ambient temperature reading in an area monitoring application or a body sensor network. • Light Intensity → estimating the total solar illumination that a crop receives over the course of a day, month or season. Smart building management, turning lights on or off depending on the outdoor light levels. • Humidity → indoor humidity control, smart crops - humidity levels are directly associated to the occurrence of certain plant diseases and pests like fungi.

  9. Application Scenarios • Atmospheric Pressure → autonomous weather stations composed of geographically separate WSN islands situated in remote locations. • Acceleration → movement detection in body sensor networks. Seismic detection.

  10. Application Scenarios • CO2 Gas → indoor air quality metering in a smart building application. • Methane Gas → leak detection in household and industrial appliances. • Diesel and Gasoline Exhaust → outdoor air quality metering. Air pollution sensing in wireless sensor networks deployed on a highway or inside a major city.

  11. Energy Storage Technologies

  12. Energy Harvesting • Technology that opens new possibilities in device portability and application functioning time. • Well suited for powering remote electronic devices (like WSN nodes) • The device is no longer battery dependent. Its functioning time can be prolonged indefinitely

  13. Photovoltaic Conversion I = IL − ID − ISH I = output current IL = photogenerated current ID = diode current ISH = shunt current Vj = V + IRS V = voltage across the output terminals I = output current RS = series resistance

  14. Network Gateway • NGW100 kit from Atmel with added peripherals • Two Ethernet ports, SD and MMC card reader, • Runs a modified Linux version.

  15. Smartphone • Android-enabled smartphone • Runs a dedicated SoNDa application • Real-time vizualization of sensor data • Interactive menus and graphs

  16. SoNDa Software Architecture • Heterogeneous WSN monitoring platform • All nodes run ported versions of ContikiOS • Measured parameters can be visualized from anywhere in the world using MonALISA (MONitoring Agents using a Large Integrated Services Architecture) • Allows data aggregation from multiple WSN networks that may even be geographically distinct

  17. MonALISA GUI
