  1. Information Fusion Visitor Lab Wireless Sensor Network (WSN) test bed

  2. WSN research in Information Fusion? • Real-time sensing in several IF scenarios • Vehicle detection, Agriculture, Situation awareness • Distributed information fusion • Larger infrastructures • Improved fault tolerance • Collaboration • Companies within the IF profile • WSN group at University of Virginia (UVA) • Two long visits to UVA • Assisted living, Medical monitoring, Environmental monitoring • Sensor integration, Leo Selavo (University of Latvia)

  3. Basic requirements • Mobile sensors and gateways (database nodes) • Off-the-shelf products • Industry standards • Open platform • Usefulness in classes too Wi-Fi Zigbee Zigbee

  4. Mobile sensor node: Crossbow Telos B • On-board sensors • Visible light, IR, humidity, temperature • Digital I/O, I2C, serial port, 8x ADC, 2x DAC • Open interface to integrate other sensors • Serial port, shared: Radio/1MB Flash/RS-232port • 16-bit RISC (MSP430), 10kB RAM, 1MB Flash • Zigbee communication • <100m, ’5x modem speed’ Battery time <7 days

  5. Mobile gateway node: Nokia N800 • ’PDA performance’ • Maemo Linux • 128 MB RAM, 256 MB FLASH • Web cam • Microphone, Stereo speakers • 2x SD slots (2x <8GB) • Touch screen (800x480pxl) and stylus • Wireless: WiFi 802.11b/g, Bluetooth 2.0 • 1x USB Battery time <12 days

  6. Open platforms • Crossbow ’TelosB’ - sensors • TinyOS and nesC • Nokia ’N800’ - gateway • Linux basedOpen source project ’Maemo’, supported by Nokia • Continous development: N810 (keyboard, GPS, faster), OS2008 release

  7. WSN lab equipment • Sensor nodes • ~20 TelosB: USB, serial TTL, digital I/O, analog I/O • ~20 MICAz: serial TTL, digital I/O, analog I/O + sensor boards: accelerometer, sounder, .. • ~10 Tiny mote (Mini-SD) • 3 Seemote • Soil sensors (SLU), Vehicle sensors (Exensor) • Gateways/Database nodes • 2 Nokia N800 + 2 GPS modules • 3 Nokia N810

  8. Next • Summer integration project • Demonstrator development • External project application for collaboration
