Exactly...

either use a /24 or /16 subnet mask, but not a /32.

Yes, /32 subnets work as soon as OLSR is running, but they don't work 
without it and make testing more difficult. No need to make things 
difficult if you have less than 254 devices.

So my suggestion would be to set each node to

IP 192.168.1.X Netmask 255.255.255.0 Broadcast 192.168.1.255

where X is a number between 1 and 254.
