Here are some of the details.

“We are pleased to announce that the /tmp/lab  will be organizing a Spring Wireless OpenWRT Mesh Contest called “Wireless Battle Mesh” during 2 days (April 11-12th) with the goal of building 3 wireless mesh networks based on embedded hardware running OpenWRT and different concurrent mesh routing protocols.

The targeted architecture will be 3 networks of 25nodes + 1 wireless managment networks (10-20 nodes) to achieve realistic size of nodes number, data traffic, configuration problems. The architecture will be set-up indoor and outdoor around the building of the /tmp/lab.

OpenWRT will be the selected for the BoardSupportPackage running on the different hardware nodes and a core network configuration will be built on Linux servers with user-friendly features such as :
*VLANs
*Captive portal
*Authentication
*Admin portal

Concerning the mesh-protocols, selected targeted protocols are :

*OLSR : IP-based mesh routing platform (http://olsr.org and openWRT package available)

*BATMAN : Layer2-based mesh protocol (http://open-mesh.org) and available as a kernel module for Linux and packaged in OpenWRT

*BABEL : Layer-3 mesh protocol developed by University Paris 6, available for Linux and soon to be packaged for OpenWRT (http://www.pps.jussieu.fr/~jch/software/babel/)

Concerning the hardware node, we are looking for hardware sponsors that could enjoy this “real-case” contest by providing 50-100 nodes……….. More after the jump.

Looks to be quite a good time for packet heads and people with a lot of time with Yagi’s.

-E.

I know I’m pretty late with posting the results of the competition, but… well, in fact, I cannot even do that =(
Unfortunately, one of my bags disappeared mystically on the last night of 25C3, and with it not only a bunch of cables and T-shirts (if by any chance you come across any of these, please let me know!) but also a bunch of paperwork – including my list of participants in the coding challenge…

Therefore, at this point I can only provide you with the times we took
at the speed soldering competition:

Group 1:
11:42 Ole
13:00 Ash
15:38 Paul
18:34 Joe
22:24 Alex
24:33 Risktaker
34:10 Dmytri
36:48 Natano

Group 2:
11:11 Marius
12:12 Andi
14:14 Zach
16:32 Rainer
16:51 Eric
17:27 Audrey
46:00 George

However, there is ONE thing I can remember for sure, thinking of the following day’s speed coding competition – that being an epic accomplishment by a boy called Matvey (if I recall correctly):
This young coder did not only finish the task (Euler problem no. 12) within less than 20 minutes, but also put together a beautiful little piece of programming art.

Now if you got hooked on our coding challenge, why not consider to join TECC, The Euler Coding Collective?
We love Euler problems – and solving them in all different languages. ^^

Again, special thanks to Mitch Altman for hosting our solderers,
and thanks everyone for taking part in the challenge!
You people rock.

Yours truly,
/astera

PS: And if ever I get my stuff back, I’ll update this post of course =)
