The Smart Sensor Web 160

Posted by timothy from the buzzword-overload dept.
Roland Piquepaille writes "As writes Vincent Tao for GEO World, integrating the billions of sensors already present in our environment with the power of the Web will represent 'a revolutionary leap in earth observation.' 'In short, the Sensor Web offers full-dimensional, full-scale and full-phase sensing and monitoring of Earth at all levels: global, regional and local.' The Sensor Web will need to have five characteristics to be successful. It must be interoperable, intelligent, dynamic, flexible and scalable. And the Sensor Web architecture will have four layers: a sensor layer, a communication layer, a location layer and an information layer. When it's here, it will have 'extraordinary significance for science, environmental monitoring, public safety and many other domains of activity.' This summary contains the essential concepts of the original and dense article."

    a sensor layer, a communication layer, a location layer and an information layer Ahhhh.

    Depending on the properties of sensors, geographic coverage, network access capabilities and, more importantly, domain applications, the physical architecture (i.e., the first three layers) can be very different. The information layer serves as a backbone and shares a commonality. This layer is a gateway to integrate and fuse observations from spatially referenced sensors. It connects widely distributed in-situ sensors and remote sensors over wired or wireless networks. Interoperability becomes a key to enable the information layer's integration capability. Uppercut.

      interoperable, intelligent, dynamic, flexible and scalable Arggg.

      Just because something is a buzzword doesn't mean that it doesn't have meaning or that it isn't important.

      • interoperable - There's going to be a ton of different architectures, software, etc. out there. Unless a system can communicate whith all of them, it can't make use of them.
      • intelligent - That's a heck of a lot of data; it's going to have to be processed quite a bit before humans deal with it, or it's useless.
      • dynamic - The sensors will be moving around and going on- and off-line all the time. You have to take that into consideration when designing.
      • flexible - If it won't be a centrally-controlled deployment, then the ability to do as much of what you want as possible with what is available is very important. Also, see 'dynamic'.
      • scalable - There are a heck of a lot of sensors. You can't say "let's have them all communicate directly with one central server." Scalability is perhaps the most important feature of any large, dynamic network.

      Sometimes things get to be buzzwords because they actually matter. Horsepower is a buzzword in the car arena, but that doesn't mean that it's not important to look for if you want a truck that will tow heavy things.

      • any global sensor net will need all of this features (and more) implictly.

        No need to state the obvious.

        A brief overview of the various technologies and protocols which endeavor to tie everything we have together, and lay groundwork for future developments would have been taken less negatively.

        Never trust vague government proposals. The amount of buzzwords in this one is just too much to let go without comment:

        • interoperable- We want to be able to spy on everything from cars to refrigerators. These various systems should be able to coordinate their spying automatically.

        • dynamic- We don't yet know exactly what we want, but whatever it is, it had better do everything we want.

        • flexible- This important spying technology will probably only be initially approved by citizen-voters as traffic-monitors or whatnot. Naturally, we want to be able to use it for other things (spying).

        It's not important at all. My inline 6-cylinder Jeep will tow more than any V8 regardless of the horsepower because it is designed for high torque and has twice as many gears. It might not go as quickly as a 454 with a turbo but it could pull a tractor-trailer if you could find a way to attach it. I think the fact that you don't even recognize the complete irrelevance of horsepower to your example makes it prime for categorization as a buzzword.

      Not quite. Smart dust (a project that started back in 1999 at the Robotics lab [berkeley.edu] at Berkeley, and which reached the prototype testing stage [eetimes.com] earlier this year) was never intended to be a global, long-term sensor network. Its strengths are that it can be easily deployed in areas which have been traditionally difficult to fit with conventional wireless sensor networks (such as battlefields) and that it is self-organizing so minimal setup time is required (again, important in combat applications -- there was a reason Smart Dust research is funded by DARPA). Neither feature is essential to the global sensor network that this story is discussing.

      The primary reason Smart Dust wouldn't be a good fit (aside from the relatively high cost of deploying it, compared to using a cheaper, less miniaturized commercial solution) is the power problem. A big challenge for networking researchers involved with this type of sensor net is that each dust "mote" has very limited power reserves, which once consumed are typically not replenishable. (There have been ideas tossed around about recharging by harvesting solar or vibrational energy, but those are just idle speculation at the moment.) This is great for something like a battlefield network, which only needs to be up for the duration of your conflict, but is unsuitable for a persistant network.

    I see they're being smart, and making a cumulative update forwarding capability in these.

    One thing I've always said a cell phone should have is the ability to pick up cell phone broadcast signals to determine which are nearby. Then, in the case of a tower outage, or straying too far away, you would switch over to a peer-to-peer version where your signal would get passed on via other phones to the next nearest tower. Hopefully this functionality would use a low quality, low bandwidth signal, so as not to disrupt other callers on the phones it's passed through.

    Of course, this would require a general reworking of the phones firmware between you and the tower, to leave a small gap of bandwidth open at all times for this forwarded traffic. (There's a good 5-10 years of rolling out phones!) The sooner some phones with this capability get rolled out, you'd ahave a slowly expanding infrastructure. However, it would greatly expand coverage area, especially in places that are just outside of the coverage area.

    These sensors use something like that to pass on data to the next nearest device with Internet connectivity. Good to see someone was thinking ahead. Just hope that capability doesn't get held back because of a budget cut or "I'm not going to pay for someone else's traffic" NIMBY arguments.
