How to connect wifi topology (ns3) to an external SDN controller?

[Rania SAHRAOUI]

Hello everyone,

1/How can we connect a Wi-Fi topology simulated by ns-3 to an external SDN controller?

2/ What I've tried so far:

Case A: ns-3 + ofswitch13 module + OpenDaylight SDN controller

• Problem: The OpenDaylight controller detects the switch connected to the Access Points (APs), (APs appear as hosts). But, the controller does not display the Wi-Fi stations in the topology, even though these stations are associated with the APs.

Case B: ns-3 + OpenDaylight SDN controller via Mininet

• Problem: The OpenDaylight controller detects a switch connected directly to the Wi-Fi stations, (stations appear as hosts). However, it does not display any Access Points. It seems that, in this case, the controller considers the AP and switch as a single component.

I would greatly appreciate any help or guidance.
Thank you!
