This is some of the stuff that I'm busy with:
High Performance Node - WEP/WPA
One of the requirements of the High Performance Node is to have WEP or WPA enabled between the wireless links of the mesh nodes. WEP and WPA are both methods enable the encryption of data before it is send over the air. WEP (Wired equivalence privacy) is an older standard and it makes use of a WEP encryption engine while the newer WPA standard added the use of an AES encryption engine.
Wireless adapters on Unix Systems can operate in three different modes: Client, Hostap (Access Point) and Adhoc mode. Most of implementations of wireless (802.11) networks are based on a model where there is one Access Point with several wireless clients attached to to it.

Wireless Mesh networks make use of the Adhoc mode of 802.11.
