Assign 4-addr net per each STA:
192.168.1.0
192.168.1.1 AP
192.168.1.2 STA1
192.168.1.3 bcast

192.168.1.4 
192.168.1.5 AP
192.168.1.6 STA2
192.168.1.7 bcast
...

Set up routing between those STAs you want to talk to each other:
on STA1: ip r a 192.168.1.4/30 via 192.168.1.1
on STA2: ip r a 192.168.1.0/30 via 192.168.1.5
