  1. Wireless Sensor Networks Studies and experiences at ISMB Torino, Italy Edoardo Calia calia@ismb.it Human Factors and the Digital Home Workshop ETSI, Sophia Antipolis, 22 October 2004

  2. ISMB • A research institution within the Torino Wireless high-tech district • 8 Technology labs: photonics, EMC and Antennas, Telecommunications, Networking, e-security, Services and Applications, Navigation services, Microsystems and materials • Joint management ISMB/Politecnico di Torino • 150 researchers (50 from ISMB, 100 from Politecnico)

  3. Wireless Sensor Networks at ISMB • One of the most recent research areas, started at the end of 2003 • Activities performed within the Networking Lab and the Services and Applications Lab • Cooperation with Politecnico di Torino Electronics and Computer Science departments

  4. WSN as a “horizontal” technology • Extremely interesting because application fields have been tested for years using wired sensor networks • Wide number of application areas • We focus on: automotive, home automation, e-health • Partnership with industries (STM, FIAT Research, Motorola, Intel), Utilities and services, Public Administration

  5. Studies at ISMB/Politecnico • Modeling of nodes and communication channel (Politecnico) • Simulation of nodes and communication channel (ISMB, Politecnico) • Location services (ISMB) • Application development (Politecnico) • Power management (Politecnico, ISMB) • Power-aware routing (ISMB)

  6. Studies at ISMB on WSN • Labs Involved: • Networking • Wireless Technologies for Multimedia • Research Topics: • Technologies • Energy-aware Routing (on going) • Nodes Localization (on going) • Location-aware Routing (planned, as a combination of above topics) • Network Synchronization (planned) • Applications • Specific topics in the automotive area (on going) • Platforms: • Crossbow WSNs (MICA2 and MICA2DOT motes) • Own simulation tools • WLAHN M. A. Spirito / ISMB

  7. Energy-aware Routing in WAHSNs • Objectives: • Gain hands-on expertise on state-of –the-art WAHSN platforms • Address a representative energy-aware functionality for WAHSNs: routing • Experimental activities from the beginning • Status: • Gained expertise on XBow development environment, including TinyOS operating system, NesC programming language, TinyDb application • Analyzed current XBow design choices, in particular ad-hoc networking (discovery, network construction, routing, etc.) • NesC implementation of an energy-aware routing algorithm on XBow platform • Performance are currently being evaluated • Next steps: • Comparison of current energy-aware solution with existing solutions • Refinement of current energy-aware solution/implementation of alternative strategies • Introduction of location-awareness M. A. Spirito / ISMB

  8. Nodes Localization in WAHSNs • Objectives: • Develop robust and distributed algorithms for location estimation of nodes in a wireless ad-hoc (sensor) network • Algorithms should not depend on the physical layer technology • Algorithms should work also in absence of anchor nodes • Start with analytical/simulations studies • Status: • Few state-of-the-art location algorithms evaluated • Simulation environment built • Some algorithms, among the most promising ones, implemented in the simulator • Preliminary analysis of algorithms performance carried out • Improvements to algorithms currently being implemented • Next steps: • Continue comparison between algorithms • Implementation of algorithms on real platforms (WAHSNs? WLAHNs?) • Combination with routing M. A. Spirito / ISMB

  9. Practical experiences at ISMB • First technology investigated: XBOW motes (pre-ZigBee) • Open OS and application code allows testing and experimenting of new algorithms and solutions • Experiments on power-aware routing: routing algorithm augmented with knowledge about the battery level available at potential next hops • Localization algorithms: simulation using laptops due to the high computing power required • Relative location estimation (no anchor point)

  10. XBOW Motes

  11. Practical experiences at ISMB • E-health remote monitoring project • Non-invasive solution to keep under control several parameters of the health status of elder people • Wearable watch-like device including temperature, acceleration, light and pressure sensors • Wireless communication to a residential gateway connected over the Internet to a service center • Demonstration involving 50 devices in 2005 • Partly funded by Regione Piemonte

  12. Remote Monitoring

  13. A student WSN lab • Agreement with Intel Research to set up a student lab within the Networking lab at ISMB (nov-dec 2004) • Access to students working at their MS degree and PhD program • Focused on Wireless Sensor Networks/ XBOW • Participation of University of Turin, Politecnico di Torino, Telecom Italia Lab, ISMB • Not an IP-oriented Lab, even though this could be an evolution of cooperation with Intel if the student lab works out well
