If you have access to the AP association table, correlate by polling that from your central monitor.

Otherwise, no - unless you send traffic to wake up the phone (not nice) you can't do much.

To compound your problem, a lot of phones (ie, android) default to disassociating wifi entirely when the screen is off, unless the user picks a more aggressive setting. It's not just idle - it's no longer on the AP. It will rejoin when they turn the phone back on. iPhone has some form of disassoc while off as well I believe.

Sorry for the bad news.
