  19. X-Sense Wireless Sensor Technology • Challenges Wireless Sensor Technology • Develop a platform that integrates • concepts for adaptive resource management (computation, communication) caused by different sensing modalities • concepts for adaptive application-level control driven taking into account available and scavenged energy, external and internal dynamic application requirements, and long term reward functions. • Develop a methodology for the design of dependable wireless sensor networks.

  20. WSN Integration in X-Sense Problem statementHow do we combine application control and resource sharing ?Can we do that with reasonable run-time overhead ?Do we obtain an adaptive but still dependable and resource efficient system ? application control … app2 app N app1 WSN server CPU server GPS server

  27. Summary • Organization: • Status: proposal, will be submitted to KTI in March. • Participants: Siemens BT, TEC • Resources (TEC): • 1 1/3 PhD positions • some material and consumables

  28. Goal From a newtestbedinfrastructuretowards on-line monitoring • Based on successfulcooperationwith Siemens BT • ExtendsObservability (MICS) towards on-line monitoring • Challenges: • Fromlocallyoberservablepropertiestowardssystem-widediagnosis; distributedreasoningaboutthesystemstateatrun-time • Balance localoverhead (precomputation, additional software, communication) andqualityofdiagnosis.

  30. Summary Table

  31. Prototype Strategy • Try to make use of synergies between platforms: • Testbed used for all projects. • Use and extension of PermaSense base-station in Open-Sense (mobile air pollution measurements). • Reuse of PermaSense sensor node in X-Sense (temperature, pressure, crack meters). • Development of a new (modular) node concept to be used in PermaSense III (acoustics), X-Sense (location).Maybe Arm/Cortex-based (with energy scavenging)? • The SwissEx data backend will be extended towards Open-Sense. Try to use this for PermaSense III and X-Sense or develop a new one that can be used for all projects.

  33. Personnel Planning • Current Status • Jan Beutel • Matthias Keller, Federico Ferrari, Marco Zimmerling • Roman Lim, Mustafa Yuecel, Christoph Walser • Matthias Woehrle, Andreas Meier (until 03/2010) • Target • 1 additional PostDoc • 3 additional PhD students (1x is already in pipe starting 05/2010)

  34. Organization • Shared responsibility Jan Beutel, Lothar Thiele • joint supervision • conflict resolution mechanism: talk to us in case of problems! • Weekly additional SN group meeting after TEC meeting • Bi-weekly reading group • PermaSense seminar for cross disciplinary pollination • meetings take place despite individual absences • SN group webpage to reflect activities (in/external)

  35. Organization cont. • Use of shared infrastructure + individual research topics • everyone has to invest in the shared infrastructure and take over responsibilities (web, deployments, testbed, lab, students) • focused research topic should evolve after first third of PhD time • Emphasize team-work with individual domains of expertise depending on each research focus • Shared literature repo svn://svn.ee.ethz.ch/tecdoc/wsn/bibtex
