This is for a research project. The idea is that as soon as a STA associates with an AP, this AP notifies another AP (at that moment out of range for the STA) to also add the STA. I won't go into much detail, but the idea is to enable seamless mobility for the STA when moving between AP's.

Could this be extended for wireless network? Would it be straightforward to just add a call to the driver (via nl80211) in function "hostapd_ctrl_iface_new_sta" (ctrl_iface.c), or do you think there are any pitfalls?

Best regards,
