The use of SUMO in ns3

[El Kinani Youssef]

Hi everybody,

I used SUMO to create a MAP for my VANET simulation. I extracted the MAP with openstreetmap and I'm confused with the number of nodes specified in the "*.rou.xml" file. I found 99 vehicles, and I don't know if I have to tune this number or rather I have to specify it in my ns3 simulation.

Thanks in advance
Youssef

Hi,

the number of nodes you create in ns-3 must not be greater than the ones in the SUMO traces. If you create less nodes, only the first ones will be picked.

Hope this helps,

T.

Yes this is what wanted to know, thank you. What if I wanted to add more nodes in the sumo traces? I didn't find how to do it in the sumo tutorial or I'm missing it.

I wanted to ask another question about enabling lte_traces. I'm getting this error:

Hi,

no idea about how to use SUMO, I never did it. I guess that there is something in its manual. Else you can try asking to the SUMO devs.

About the error, you're trying to connect a function with the wrong signature to a TracedCallback (apparently your function has an extra param at the end).

Another possibility is that you did modify the sources and/or that the bindings have to be regenerated.

Before rebuilding the bindings I'd double check the other possibilities.

Hi Youssef,
I need your help in implementation of some another map extracted from Open street map and use it with Vanet-routing-compare example in ns3.

I got this error

Kindly help

Hi Dpk Rohilla,
have you find any solution for the problem? I am also getting the same error.


Thanks and Regards,
