Scalability issue with 200 stations in Mininet-WiFi: hardware limitation or framework constraint?

[ELENA VENTURA]

Hi everyone!

I’m working on a vehicular network simulation using Mininet-WiFi.
In my setup, I have around 200 vehicles, and I want to assign one station per vehicle to simulate the wireless connection of each vehicle to urban access points (APs).

However, I’m experiencing instability and blocking issues when the number of stations grows beyond ~10. The simulation becomes very slow or stops responding.

My question is:

Could this issue be related to hardware resource limits (e.g., CPU, RAM, number of cores, virtualization overhead)?

Or is there a known limitation in Mininet-WiFi, such as the maximum number of hwsim interfaces or the number of stations that can be handled reliably?

Essentially, I’d like to understand whether this scaling problem originates from my system’s hardware resources or from inherent limitations in Mininet-WiFi’s architecture.

Thank you very much in advance!

This is a hardware resources issue.
