Systems Wireless EmBedded 1/18/2002WEBS Retreat Breakout1 Feedback Lakshman Krishnamurthy –Best retreat so far –Lots of good progress since last retreat –demos much more polished, significant progress from surge –tracking and database cool, visualizations valuable –first cut at real world app (habitat) wonderful, do more »driving requirements that otherwise might not have through about –demo cause integration of many pieces. »need to think more about how the pieces come together loose vs tight coupling –simulations nice, but do more real-world valuations

Systems Wireless EmBedded 1/18/2002WEBS Retreat Breakout2 David Tennenhouse Enthusiastic observations –something very exciting about to happen »collect all this sensor info to the ip edge »opportunity to take advantage of this data in all sorts of ways »connected to matlab, plugging things together in interesting ways »wrapping data from motes at gateway into XML »enable ways of getting real-time access to data as never before, but... need to get it to where it is pluggable into useful tools »will drive a virtuous cycle... please wrap it in XML –SQL was thrilling – had to be done and very valuable »just the starting point, but shows what a difference it can make –neat to see the control loops appearing »DT had just about given up »huge challenges lurk there almost all the theory assumes fixed time constant in control loop,... much of this simply hasn’t been tried tremendous opportunity to rewrite the books

Systems Wireless EmBedded 1/18/2002WEBS Retreat Breakout3 DT –great to see work on security »next year, should nail down what we do need »have a huge lead, so go set the benchmarks pay attention to the gateways, within,... what is the base level? compare power budget,... rather than lowest common demoninator great opportunit –Chance to rewrite the book by going back to simpler world with better tools »another example: static checking in programming env –the programming environment work has huge potential »demonstrate in this environment and then it may strongly impact rest of the world Challenge: What are the other chances to ‘get it right’ while things are young? –didn’t invent another DOS,...

Systems Wireless EmBedded 1/18/2002WEBS Retreat Breakout4 Wei Excellent retreat, lots of progress, delivered on plans from last retreat Previous feedback – big issues both addressed –Real applications –Higher level programming models Watch out for lots of redundant approaches emerging Continued effort on routing is valuable. –Need one still. Many demos limited by loss rate. –environments are mostly not that dynamic. How much adaptivity is right? testing is necessary –regression suite, not break other folks code

Systems Wireless EmBedded 1/18/2002WEBS Retreat Breakout5 Gordon currently a terminal, since not IP forming a new computer class –once a decade –you are inevitable (historically) »can learn from it (3 spins of moores law ahead) –form taxonomy –nail operational parameters to define problem subspace build app-down Are we operating at too many levels? Effector nets Think about what an industry would look like around this MoteCAD to design the overall mote networked system

Systems Wireless EmBedded 1/18/2002WEBS Retreat Breakout6 Arati Thanks Everything discussed was of interest, productive, and lots of fun Allowed me to think more about the global picture in my own applications / algorithms Habitat monitoring really good robo and structure monitoring gave insights into additional applications as possible valuable to learn more about TinyOS, ex NesC and many other aspects that would like to use would like to see more about debugging and testing really like to produce in many parts going forward (CC1000 stack)

Systems Wireless EmBedded 1/18/2002WEBS Retreat Breakout7 Falk Thanks, very enjoyable, generated new ideas Really impressed by progress (demos, real world applications) –something real and tangible NesC especially important step Like to participate in security Volunteer to demo at next retreat Too bad so many left before last day. Can we get two full days?

Systems Wireless EmBedded 1/18/2002WEBS Retreat Breakout8 Paul Thanks. Great. Really enjoyed meeting. Impressed in size of community, breadth & depth of effort Demos outstanding. Springboard to see how to adapt to real world business problem –ex casino’s tracking minors, lost person in theme park Great presentations (even if JIT) Query processing great, also tool development volume of routing and localization suggest concern over those aspects –important to nail these, as many others depend on them will be increasingly to present information, not just data –wrap with XML,.... encourage to continue to seek out case studies –ind. talks will expand view postulates –battery life is never long enough => power mgmt, gen –each bit transmitted is loss of life => protocols –make it cheap and simple, (reliable and quick to market)

Systems Wireless EmBedded 1/18/2002WEBS Retreat Breakout9 Mike Very productive, great one disappointment –low power operation –would like to see permanent network running for long time »get long term network installed in Cory/Soda –every presentation should consider 1% usage –std battery life indicator in message (like security) »or heartbeat messages that are integral fantastic
