 From my experiance a DHCP lease is renewed 1/2 way through the lease. 
So if you have a 60 min lease then it would be renewed every 30 mins.
I'm not sure of the exact state machine of most devices but I do know 
from logs that most laptop's try to renew an existing (or previous) ip 
address. I don't know what embedded devices (such as iphones etc) do.

What is the network topoligy, is coova-chilli running on an access point 
(such as with openwrt) or have you got a server with 1 or more AP's / 
devices connected via a switch?

As for re-authing a session if that would be implemented I know I would 
prefer it to be a configurable option (or at worse a compile time 
option). Having EVERY DHCP request turn into a radius request could 
cause a significant volume of traffic.
