Each backbone node has two ore more peer to peer decicated links with others backbone nodes and may or may not have an access point offering access to awmn and maybe to the internet.
(at least two wireless network interfaces)

Clients nodes are nodes which simply connect to an access point of a backbone node (only one wireless network interface).

There are currently around 300 backbone nodes and around 400 client nodes.

Currently no peering agreement is made between the nodes but that is a big debate going on right now…

I should also mention in my previous post the homepage of the wind project which is wind.cube.gr
Maybe there you will be able to find more info in english but i suspect you already found that.

At this url http://info.awmn.net/users/cpg/index.php?cat=2
there are some photos of the installations made by backbone nodes.
Enjoy

I did a babelfish translation, but couldn’t really make out what was going on. It’s a nice looking map though. Lots of features, lots of nodes. How big is AWMN, and is it an ad-hoc community of APs or more of a cohesive network structure that follows a pico peering or freenetworks type agreement?

I also took a look at the topology of Athens (and Tripoli) in Google Earth, looks like you have excellent conditions for wireless.

Awesome stuff.

Btw it is open source an maybe you could use it if it feets your needs….
