The Smart Sensor Web

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.

      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.

  14. No reliance on a single "tower" by erpbridge · · Score: 3, Insightful

    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.

      Unsurprisingly given how many smart people are working on wireless these days, systems like this have been discussed frequently in the past. The primary reason we don't see this isn't actually the channel allocation and spectral efficiency issues you mention; it's a much more simple problem. While most new cell phones have standby times on the order of up to a week, the actual talk time (by which they usually mean when data is being transmitted) is usually only a few hours. How many users would go for a system where just a few hours after recharging their phone they ran out of juice because it was busy relaying someone else's call to the nearest tower?

    It looks like Smart Dust
    Not quite. Smart dust (a project that started back in 1999 at the Robotics lab at Berkeley, and which reached the prototype testing stage 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.

In the air, we only know about the upper atmosphere generally through the sparse, limited use of radiosondes (weather balloons that track back results via radio and can also be tracked from the ground with radar to figure out wind speed and direction). Unless we start seeing swarms of self-propelled flying sensors (a'la "Batteries Not Included"), I don't see "full-dimensional" coverage of let alone the atmosphere on the earth.

    The description "The Smart Sensor Web" concentrates on 'plumbing', that is, just getting data. The description is too light on the rest that is needed for real usefulness.

    The description appears to fall into an old trap, the promise that with all the data we have 'everything'. Yes, getting the data is usually necessary. However, the data alone is rarely sufficient and, thus, not yet 'everything'. So, we also need (1) dictionary of the data, that is, what data is where (e.g., what Google does for the Web), (2) descriptions of the data, e.g., as in XML, the older OSI CMIS/P ideas, and/or just natural language (the sensor web data will usually not be self-documenting -- there is a challenge here not faced by the Web), (3) what we are going to do with the data (we can't expect just to have humans read it), and (4) what the real and valuable applications are (not the news and entertainment of the Web).

    The description did mention "intelligent" and "information layer", but it is here that the crucial issues are for power and value; thus, we need much more than just the simple mention.

    Broadly we can compare with the Web -- TCP/IP with HTTP and HTML: The Web mostly presumes that the server is sending to a PC with a human reading a screen. So, the Web got to exploit the ability of humans to read screens.

    For sensor webs to yield valuable results, we need some powerful automation of the data, need to replace the human reading a screen. There is value here but also challenges.

    A guess: Too soon, we will want more than just 'sensors'. We will also want 'transducers' that let us 'control'. Also, we will need security, etc.
