Unmanned Aircraft Clustered via Bluetooth
An anonymous reader writes "Researchers at the University of Essex are using Linux and tiny embedded computer modules to build fleets of unmanned aircraft that fly in flocking formations like birds, while performing parallel, distributed computing tasks using Bluetooth-connected Linux clustering software. The Gridswarm project includes model trainers that can fly 120mph, while a parallel Ultraswarm project uses co-axial helicopters. A prototype of the later is believed to the world's smallest flying web server. The aircraft will run Linux on embedded computing modules from Gumstix."
As an A-LIFE dork I think the fact that they got these planes to exhibit true (if they arent lying little light on details) flocking behavior, it's not hard to make things flock it takes basically 3 instructions.
1) Follow the plane/bird in front of you
2) Go about as fast as the plane/birds around you
3) Don't hit other birds/planes, keep a reasonable distance.
Emergent behavior is really amazing if you are interested in it some more check out alife9.org Its the website of the last alife conference in boston that took place over the summer, really neat stuff in there.
I saw this on an episode of tale-spin once
I'm amazed that the article didn't include any references to "Homeland Security" or "fighting terrorism". Doesn't it seem like every single goddamned new idea, or retread of an old one, gets stretched in the marketing to push the security applications for terrorism?
Where there's money, though...
Sounds like something out of Michael Crichton's Prey

I agree with the why; no matter how cool it would be to be sniffing for wifi and running across the webservers' routing from my home machine, it seems silly to exert so much effort (read money) for the effect. Maybe is is useful for someone who does not want their website to be tracked by big brother(tm)... which is feasible in the US now-a-days. Yet just by doing that, one would need to be using open AP's that one is flying by, just asking for Federal Freddy to not so proverbially nail your ass to the proverbial wall.
Yet I disagree with the blimp. You have to be able to upload your requests, meaning you will need an amplified radio to communicate to the blimp, leading to alot of crosstalk. Same problem with the orbital idea. If you want to solve this problem with uber-transmitters like satellite dishes, you are looking at (i dont remember exactly from cs 428, but somewhere in the range of) 128kbps u/l and 64-48kbps d/l.

The following are obvious ideas, but maybe publishing them could prevent patenting.
* A queue of cars is also like a flock
* Onboard computers can co-operate in helping drive the cars, or entirely drive the cars
* The cars can use a suitable operating system, such as Linux.
* The cars can communicate through radio, light, sound etc., using any protocol, for example blue-tooth.
* At a junction, any car can choose to leave its current flock and join one heading more towards the car's destination.
* Each flock of cars uses external navigation information from satellites, broadcast radio, networks such as the Internet, contactless chips in the road surface, etc.
* The flock co-operates to receive navigation information, giving greater total bandwidth and better positional accuracy.
* Flocks share information with other flocks, reducing the effect of traffic jams.
* A car can reserve a parking place or other service, to be ready as (or just before) it arrives.
* A driver can pay money to adjust the priority of his or her car, giving it priority when cars decide who should overtake, or who should go in the "fast lane", or park closest to their exact destination.
I can see how parts of this might be interesting in a military application. Run several UAV's in formation with one person controlling them. Use the bluetooth to enable them to triangulate positions and keep from getting too close to one another.
I was thinking something similar, except more along the lines of 'the days of the strategic bomber are numbered'.
Clusters such as you describe might be the killer defense that could render the strategic bomber vulnerable and obsolete.
In the free world the media isn't government run; the government is media run.
And as you say, there's builtin redundancy, so that maybe the cluster could decide to risk a member by letting it peek around or over an object while the main group stays safe. Also, members could be "dropped off" to act as communication relays if necessary. And then there's the attraction of having multiple eyes viewing the target from different directions...
How about a swarm of high altitude balloons that form a telescope array? using their fans, they can stay in relative position to one another.
