  1. SensorWebData Fusion in Large Arrays of Microsensors Final MURI Review Meeting Introduction/Overview Alan S. Willsky December 2, 2005

  2. The Day’s Agenda • Introduction/Overview • An Overview of Our Research • Summary

  3. Intellectual Themes • IT-1: Consistent (or manageably inconsistent) fusion of networked, myopic sensors • IT-2: Fusion of heterogeneous sensors in unstructured and uncertain environments • IT-3: Wireless networks, network communication and information theory

  4. Functional Themes - I • Where are we? • Sensor localization and calibration in distributed networks • What’s out there? • Source localization • Feature extraction for association and classification • Multisensor fusion for data association and tracking • Multisensor fusion for other tasks (e.g., mapping of terrain, weather, etc.)

  5. Functional Themes - II • Who does what? • Making good use of available resources for desired purposes • What are the limits? • Bounding what is possible. • Pervasive sub-theme to all of these: • Working under energy constraints

  6. Who’s who • MIT • Faculty/Senior Investigators: Willsky, Mitter, Jaakkola, Fisher, Cetin, Tsitsiklis • Post-docs, visitors, grad students: 26 • Princeton • Faculty/Senior Investigators: Kulkarni, Verdu • Post-docs, visitors, grad students: 14 • Illinois • Faculty: Kumar • Post-docs, visitors, grad students: 13

  7. Website: Comprehensive record of accomplishments and activities • The Website: http://sensorweb.mit.edu

  8. Publications, Presentations, and Recognition • Publications in journals, conferences • Peer-reviewed journal: 94 • Conference/Workshop papers: 160 • Manuscripts under review: 24 • Numerous (> 40) invited, keynote, plenary talks • Numerous major awards, including • Kumar: 2006 IEEE Control Systems Award • Mitter: Russell-Severance-Springer Chair (Berkeley) • Willsky: 2004 IEEE Donald G. Fink Award • Verdu, Willsky: 2005 Honorary Doctorates • Students: At least 5 Best Conference Paper Awards

  9. Collaborations, interactions, and impact associated with our work (more later) • Our work has had significant influence in the academia • Invited talks and keynote lectures • Citations of our work • Numerous positions on key conferences, journals, etc. • Collaborations and placement of our students • We have had numerous direct interactions with DoD programs and researchers, e.g.: • CTAs (Moses) • Collaborative research (Sadler/Cetin) • SBIR Topics • We have had numerous interactions with industry aimed at transitioning our work, e.g.: • BAE-AIT (formerly ALPHATECH)—DTT, NetTrack, Raptor, … • PARC (through one of our former students) • Lincoln Laboratory (through current students)

  10. Agenda - I • 8:30 – 9:00 Welcome/Overview • Lavery, Willsky • 9:00 – 9:45 Where are we? • Willsky, Fisher • 9:45 – 11:30 What’s out there? • Willsky, Cetin • Verdu, Kulkarni • Willsky • 11:30 – 12:45 Lunch

  11. Agenda - II • 12:45 – 2:25 Who Does What? • Fisher • Mitter • Tsitsiklis, Jaakkola • 2:25 – 3:15 What are the Limits? • Kumar, Verdu • 3:15 – 3:45 Conclusion • Willsky • 3:45 – 4:15 Government Caucus • 4:15 – 4:30 Preliminary Debrief
