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.



WSN Integration in X-SenseProblem 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 ?

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



Goal

From a new testbed infrastructure towards on-line monitoring

Based on successful cooperation with Siemens BT

Extends Observability (MICS) towards on-line monitoring

Challenges: From locally oberservable properties towards system-wide

diagnosis; distributed reasoning about the system state at run-time

Balance local overhead (precomputation, additional software, communication) and quality of diagnosis.

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.

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)



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)



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
