open80211s.org is an interesting project to open up the IEEE 802.11 industry standard for wireless mesh networks. Current mesh networks are based on mesh routing software working on higher network layers and on the 802.11a/b/g standard hardware. Mesh-Routing with the
802.11s standard is intended to be more efficient as the routing is "happening" at the MAC layer.
open80211s is a consortium of companies who are sponsoring (and
collaborating in) the creation of an open-source implementation of the
emerging IEEE 802.11s wireless mesh standard. The resulting software
will run on Linux on commodity PC hardware.
Goals
* To create the first open implementation of 802.11s.
* To let the world use it, understand it and contribute to it.
* To connect all the Linux devices in the world to One Big Mesh.

IEEE 802.11s ist eine bisher noch nicht angenommene Teilspezifikation des IEEE 802.11-Industriestandards
für drahtlose Netzwerkkommunikation. Ziel von 802.11s ist ein
herstellerunabhängiger Standard zur Einrichtung von drahtlosen, vermaschten Netzwerken.
Im Unterschied zu derzeitigen Mesh-Netzen, die auf vorhandener
802.11a/b/g-Standard-Hardware und auf höheren Netzwerkebenen
arbeitender Mesh-Routing-Software basieren, findet das Mesh-Routing bei
802.11s in der MAC-Schicht statt und ist daher wesentlich effizienter,
insbesondere auch in Hinblick auf Hardwareanforderungen und
Energieverbrauch. (Version 3.2. 2008, 14:30, http://de.wikipedia.org/wiki/IEEE_802.11s)IEEE 802.11s is a draft IEEE 802.11 amendment for mesh networking, defining how wireless devices can interconnect to create an ad-hoc network. 802.11 is a set of IEEE standards that govern wireless networking transmission methods. They are commonly used today in their 802.11a, 802.11b, and 802.11g versions to provide wireless connectivity in the home, office and some commercial establishments. It extends the IEEE 802.11 MAC standard by defining an architecture and protocol that support both broadcast/multicast and unicast delivery using "radio-aware metrics over self-configuring multi-hop topologies."
