Simulating mixed g/n (2.4GHz) and a/n/ac (5 GHz) in ns-3

[Gabriel Arrobo]

Hello,

I have been trying to run an script creating an AP using 802.11n or 802.11ac and having mixed STAs (g/n or a/n/ac). I was checking the mixed-bg-network.cc example and when I change the standard for the AP to 802.11n-2.4GHz (and the sending STA is 802.11g), I get 0 Mbps as throughput. When I use my own script, I get an error message from the MAC LOW about MCS8 and MCS9.

My ultimate goal is to simulate a "real" WiFi network where an AP may have two radios (a node with 2 WiFi NetDevices) 802.11n in 2.4 GHz and 802.11ac in 5 GHz and a mixed number of STAs (802.11g/n and/or 802.11a/n/ac). For example, having two STAs (one with 802.11g and another with 802.11n-2.4GHz) sending packets to an AP (802.11n-2.4GHz). Is it possible to do this in NS3? If so, can you please provide some pointers on how to do it?

I would appreciate your feedback.

Thanks!

Gabriel

Hi,

check with ns-3-dev. if the problem is still there we'll need more details about your script.

Hi Tommaso,

Thanks for your reply. I think I was able to address the issue.

Best regards,
