The Future Of Wireless Sensor Networks

Frisky070802 writes "In the 12/03 Wired, Intel's Tiny Hope for the Future describes a fundamental transformation as Intel's Research director David Tennenhouse realized the importance of sensor networks. He saw a Berkeley project on 'motes,' little sensors that communicate on ad-hoc wireless networks. 'The company now foresees networks consisting of thousands of motes, located wherever there's a need for data collection, streaming real-time data to one another and to central servers. Intel imagines the day when every assembly line, soybean field, and nursing home on the planet will be peppered with motes, prodding factory foremen to replace faulty machines, farmers to water fields, and nurses to check on something unusual in room E214.' Intel was impressed enough with the technology to fund a whole 'lablet' to develop it. Intel sees a huge potential market in developing both the sensors and the computation to process the huge amounts of sensor information. If this rings any bells, note that the Intel lablets are also behind the Planetlab Internet emulator, previously discussed in Slashdot."

  1. originality? by potpie · · Score: 4, Insightful

    Is this idea all that original? It seems to me like this is the kind of thing imagined for wireless communication from the start. We already have wireless communication. We already have programs to monitor things and send data. Is it that inventive just to combine the two?

      I believe the inventive concepts here are using mesh, instead of conventional, networks, and having many, many dumb sensors relay information to a smart server (this is done some, but not in the diversity of environments which this inquiry explores).

      These things have not really been comprehensively explored before.

      Heck, we're still waiting for cell phone / WiFi mesh networks, and this is much more aggressive than that.

      Is this idea all that original?

      Not at all. Our body has sensors all over it - we can feel when something touches us with a pretty precise resolution. We also sense heat/cold, wind, wetness, and so on. Amazing.

      We are the ultimate "machine." Emulating ourselves and nature is a smart way to go.

      Where we seek to overcome our weaknesses will turn into specialization. Computers can crunch numbers and correlate raw data faster than we can, but that's their specialized purpose. We, on the other hand, could be dropped on Mars with sufficient of supplies and automatically adapt and survive. We might stub our toes sometimes, but for that weakness we gain in other areas. Someday computers may stub their "toes", too, in order to gain some of our special qualities.

  2. Re:Network radiation by plover · · Score: 4, Insightful
    I doubt it. These things are going to be tiny, which means tiny sized batteries, which means they can only sip very tiny amounts of power, which finally means they can only transmit very very tiny amounts of radiation.

    Here's an analogy: think about the visible-spectrum radiation emitted by an LED. Are you concerned about sunburns or skin-cancer from LED radiation? (If so, I'd like to see your computer room...) These motes will be capable of transmitting similar amounts of power. I doubt very much that they'll adversely affect anything with their radiation.

    Their bigger impact will probably be the damage done by the adhesives or fasteners used to stick them to their monitoring posts, or by the hazardous wastes left behind when they're done using them.

    This is a really cool idea

    Doesn't the whole concept seem kind of Orwellian? Doesn't the following quote from the article disturb you?:

    Deployed the way Tennenhouse envisions, the networks will require zero human input. We'll reap the benefits without having to interact with the networks, and Intel will eliminate a long-standing obstacle to its growth: the feebleness of the human brain. "Sensor nets let us relieve the human being of the responsibility of drawing information out of the physical world," says Tennenhouse. "We need to have computers anticipating our needs and sometimes taking action on our behalf."

    It bothers me - sounds like SkyNet or something. Not to even mention the environmental waste/radio interference for all these machine.

    At this point: neither.

    That's the beauty of an off-beat R&D lab. They're given free rein to develop just about anything without regard to need OR profit.

    AT&T and IBM both funded labs like these for years. They were responsible for developing such novel and diverse things as transistors and scanning tunnelling microscopes. The goal is, of course, that they will develop a product that fills a real need, which in turn will create a demand for their product appeasing their shareholders.

    I think it's absolutely terrific that some industries are able to risk investing in the totally unknown. It was truly a shame when Bell Labs dropped their unfettered research. It was also disappointing to see IBM drop research for all but computer-related work. But even so, their Zurich labs have recently come up with some novel storage mechanisms leveraging their decade-old scanning tunnelling work.

    Regardless of whether these labs prove to be duds or if one of them creates the transistor of the 21st century, the money is being well spent. Exploring the unknown is always of value.

  5. "Something unusual in room E14?" by vudufixit · · Score: 2, Insightful

    Like the patient's vitals somehow slipping and not being noticed despite the perfectly good monitors used currently in hospitals? I'm reminded of an urban legend said to take place in a South African hospital. Seems that whoever occupied a certain bed in the ICU would kick off during the night. Turns out that the night cleaning person would unplug the breathing machine for that one patient in order to run a floor polisher.

  6. Well... by Azureflare · · Score: 4, Insightful
    Isn't it possible to have maintenance bots that are utilized by the "smart" computer, and when the "smart" computer isn't able to receive or send stuff to one of the "dumb" motes, a maintenance bot or two goes out and cleans up the "dumb" motes remains? Once this idea gets really powerful, I could see this happening. (though the AI required still has a ways to go..)

    Also, I think you're right about the orwellian aspect; but I figure this is going to happen anyways. Technology is powerful. There are those who wish to hold power over others. If you look at history, you'll find a hell of a lot of the buggers! And those who want power, will find these wonderful new tools, and put them to their uses. I don't like it, but I think it's the other edge of that double-edged sword called Technology.

    The only solution is to (a) put into place systems to keep those people from abusing the technology or (b) wait until they abuse it, and hopefully a structure will come into place through intense struggle that will keep it from happening again.

  7. How convenient... by jdybnis · · Score: 4, Insightful

    How convenient...for a company that sells microprocessors ;). As market the penetration of PC's approaches 100%, Intel envisions a future in which everybody needs to have thousands (or millions) of devices with a microprocessor, instead of a just a handful. And of course they require zero human input. Nobody could operate or pay attention to thousands of devices at once.

  8. Batteries remain a big problem by Animats · · Score: 4, Insightful
    The big problem with all this stuff is that it runs on batteries. We have too much stuff now that needs battery replacement. If it transmits much, it's going to need more power than a coin cell can provide for a year.

    Wireless power transmission is a possibility. At low power levels, it's quite feasible. That's how RFID tags work, after all. In controlled spaces, like hospitals, airports, aircraft, and prisons, it could work.

  9. Telemetry and control by basingwerk · · Score: 2, Insightful

    This sounds like the right thing for telemetry and control systems. Perhaps they will fit them in the wing flaps and engines on airliners, so they don't need to go to the expense of laying wires or fibre. Or maybe they should fit them in the reactor core of nuclear power stations, so that the reaction can be moderated if it gets to hot. Again, they wouldn't need to go to the expense of laying wires or pneumatic lines. These would be good tests of thier reliability. Another application would be for the brakes on our cars - no need for a cable, just transmit a signal with a mote. Are there any downsides to this technology?

  10. Unfettered research by dpilot · · Score: 2, Insightful

    I agree wholeheartedly with what you say about the days when Bell Labs and IBM Research did unfettered research.

    Unfortunately, these companies were under "market attack" by companies like Dell, which does no technical research at all. They're also under "analyst attack" by Wall Street types measuring progress one quarter at a time, with little eye to the long term.

    The logical consequence of this is that research gets "focused," unfortunately.
