Even simpler than that, I would image. If you've got thousands or tiny systems operating independently out there and chatting on the network, and they suddenly all fell silent, then you have a pretty good idea that something is going on.
Although, I suppose a really sophisticated army could capture all of the network chatter for, say, half an hour, then zap the sensors.
To fool the network, just play back the network chatter with updated headers on all of the packets with an updated time stamp.
Re:Dusting of sensors (Score:1)
Also, the networks are very sensitive to detecting false information. There are many safeguards to prevent these kinds of "byzantine attacks". Remember, these are to be used in battlefield situations, so the army isn't going to allow any crafty enemies to disable the motes except physically.
Re:Dusting of sensors (Score:3, Interesting)
Also the more of them you sprinkle the less power they need to use because they are a mesh network, they only have to talk to their neighbors. I would assume that motes would always be operating in least-power modes anyway, so they will be using as little power as possible when sending signals. I suspect it will be less trivial to pick this up than you think. Using MEMS technology today and nanotechnology tomorrow (but tomorrow never seems to come) you will be easily able to construct positionable directional antennae enough to where motes could reasonably do point to point communication and be near impossible to detect without being within their area of effect.

The big value I see in this is in networking, and communications. Cell phone towers, tv stations, and internet backbones could in theory be replaced by spreading smart-dust arround town. The dust would automatically route from particle to particle to the correct phone, tv station, radio station, or internet IP address according to how you accessed it, and even automatically figure out the correct protocool. You wouldn't even be required to subscribe to an ISP or an pnone service provider, the dust would just route independently. if you needed more bandwidth in your connectivity, simply buy a bucket or two of smart dust and spread it arround, perhaps walk along the road and spread it arround like seed, or put it in a medium sized area and 50billion smart dusts will act and behave like a single transmitter.
other cool application I could see are painting your sterio on the wall. the smart dust in the paint would automatically configure itself to resonate and listen to your voice to tell it what radio station to listen to, it would tune to the station and then vibrate sounds accordingly in perfict coordination. the same logic could be used for painting a tv screen on the wall, where smart dust could be configured to emit coordinated frequencies of light rather than sound.

Fooling the sensors into believing that something is moving isn't very difficult. They're light-sensitive so a cloud in front of the sun might trigger it. However, these are somewhat minor problems that will be solved shortly.
The biggest problem is an enemy attempting to confuse the network. However, the network has many safeguards built in with the intention of preventing, detecting, and avoiding any such attacks.

So what's to prevent people from spreading this stuff in public washrooms/baths/changing rooms to spy on people while they undress?
What's to prevent this from being sprinkled onto unsuspecting passerbys and used to basically stalk them and their children?
What's to prevent this from being used on ATM machines or any other place where sensitive information needs to be kept secret from prying eyes and people who seek to commit fraud?
What's to prevent people from using this to gain insider information by spreading it in corporate meeting and board rooms while they are visiting, at production factories during a tour, or even at random hotel rooms for the heck of it?
What's to prevent the abuse of this technology?
I'm not saying the technology doesn't have great and beneficial uses. Military and Security uses come to mind. As does scientific research and observation. It can go a great way to help prevent spousal abuse and domestic violence, tell us when children ARE being abused or if fraud is being committed. It can even help to serve as an effective way of adding home security without all of the cameras. And help to monitor the weak and sickly who might otherwise not be monitored effectively through normal means.
I'm just left wondering whether or not this is a tool/technology which will essentially erradicate privacy.

The general feeling I got from the article and from the background site is that each of these are essentialy DSP units, providing the necessary filtering before sending the data back.
I'm not so much afraid that each of these little bugs would have a video camera. But I am concerned that together, they could be used to reconstruct the light they percieve and/or sounds/RF patterns.
I guess my fears stem from where I see the technology heading or could be heading.
I definitely agree with you that a high energy RF sweep would essentially disable most, if not all, of the bugs. But then again, how many of us cary tesla coils or emp pulse generators in our pockets? ^_-
Even down to the size of a dollar bill or a half dollar. You could pack a wireless bug that can broadcast 400-500 video lines worth of resolution with sound from commodity parts. These folk are working with scaled down component kits.

A world without privacy. (Score:4, Insightful)
No one would would be in any doubt about whether or not Iraq has weapons of mass destruction. No crime would go unsolved. No one would expect to get away with cheating on their spouse. Lying in general would become far less common. There just wouldn't be much to lie about which couldn't be verified by someone who wanted to.
Of course you would have to get used to the idea that six billion people could, if they wanted to, watch you take a dump every morning. But somehow I suspect that the excitement of voyerism would wear off if every act became a public act. Who knows, maybe we would all be happier if there was no longer any point in maintaining a public mask to cover our private lives.
I worried at first that total surveilence would lend itself too well to totalitarianism. "No crime would go unsolved" really just means that if you do anything the state disapproves of then it would not go unnoticed. But then it occured to me that totalitarianism would have a hard time getting established if eveything happens in the public view. Politicians could not cut deals behind closed doors, the military could not plot coups, the state could not lie to the people about what it is doing.
Living in a world like this would be really different from living in the world as it is, and it would be uncomfortable to people like us who are used to a good deal of privacy. But it wouldn't necessarily be bad - just very different.
Of course total surveilence is not going to happen any time soon. What will happen is an increase in certain types of surveilence by certain people. The way I see it, the problem with this is that we might wind up with a world where the state can watch the people, but the people cannot watch the state, or a world where the US knows exactly what Iraq is up to, but no one knows exactly what the US is up to. This kind of world really would be bad.
So here is a suggestion. Perhaps instead of trying to stem the tide of surveilence, what we should do is try to make sure that it washes over everyone evenly. If the state has this technology, then push for the same technology to be made available to private citizens. If the state wants more information about the people, then push for a more open government, so that the people will also have more information about the state.

I thought seriously about discussing this idea in my original post. A number of ethical theorists like Bentham and Locke thought that the idea of constant observation by God was a key part of moral consciousness. Religious people who take this idea seriously are always in a position of having to think about what their behavior would look like from God's perspective. Bentham actually proposed that prisons should be built, so that the inmates were literally under constant observation, in the hope that they would get into this habbit of thinking (his plan which he called the "panopticon" has actually be implemented in some places).
I am an athiest, but like Machiavelli I am willing to consider the possibility that religion might serve a useful social function even though it is strictly fiction. Still it seems to me that there are serious problems with the idea of grounding morality in religion. For one thing it is getting increasingly harder to maintain the fiction. For another thing, people who think that God is the source of all value are prone to forget that it is really individual human lives that matter. When that happens they tend to do horrible things even though they think God is watching.
