Thank you for your suggestions. I have already tested a Carambola 2 that is similar to the Arduino Yun and it works quite good, but as you have already mentioned it does not have 5 GHz support.

The openmesh device looks good, but unfortunately it is too expensive for a large-scale deployment (and my budget).

It is very sad that chips and reference designs for WiFi are not publicly available.

Greetings,
Florian

I think that it not easy to get 5GHz radio and Arduino Yun only has
2.4GHz support.

openmesh has 5GHz radio support and should have OpenWRT support soon.

Hi,
in order to build up a large 802.11s network for research purposes, I am
currently searching for a possibility to assemble low priced WiFi hardware.

Although, compared to IEEE 802.15.4 where you can just put a well
documented ATMEGA256RFR2 (or another comparable IC) on a PCB, it seems
much more difficult. I am dreaming of building an open source hardware
running Linux, with a (preferably 5 GHz capable) WiFi chip, that can be
used as a 802.11s node.

Although I haven't used it personnaly, I believe Arduino Yun should be
capable and might already be what you are hoping to build.  It has an
AR9331 on board and has an OpenWRT port.
