As seen on NetSec, the SANS Institute has a nice article on building a wireless instrusion detection system using OpenBSD, using arpwatch, fping, xprobe, nmap, and NBTScan.
The script that is run in the deployment of WIDS has three purposes:
1) to provide a way to identify new hosts on a wireless network,
2) to collect info that is useful in identifying these hosts, and
3) to provide a method of notification to the home admin.
The article can be seen here.
