If your WAPs support SNMP, you might use Net::SNMP to poll them. Or if they have a web interface, you could use WWW::Mechanize to scrape the log.

If it has both, I'd recommend doing it over the web interface rather than the SNMP interface - SNMP is a giant pain in the butt, IMHO. But maybe I'm still scarred from an old web-based switch manager I was forced to maintain.
