Hi,

I was working with ns3 (without SDN platform) and your modifications to make handoff and I had this issue:

We I set the MaxScanningChannelNumber to 4 and 2, I have the next error:

error

Any idea about this?

Thanks in advance.

Nelson Cardona.

It seems that the emulation gets stuck at yans-wifi-phy.cc, line=442, because does not fit the assert.

NS-3 emulation result depends on emulation script and NS-3 libraries. Since we does not know the content of your emulation script, and your NS-3 libraries are not based on our version. We can say that maybe the problem is at YansWifiPhy, StaWifiMac, Emulation Setup, or something else. But we can not give a determined suggestion, may be running emulation with gdb and use backtrace to figure out what is going on is a good step.

Thanks for the answer.

If I attach the script, can you run it on your version of ns3 (3.22) and see if you have the same error?

Thanks un advance.

We suggest you to build environment and test by yourself. Since it is an NS-3 issue, post the issue with detailed description in ns-3-users may also help.
