[ndnSIM] Mobility Model and Trace File

[IHK Niad]

Dear Ygor,
Thank you for the response.

I will be downloading SUMO tool and start experimenting with.

Am still not clear about the procedure for extracting few metrics like
Interest Satisfied, Interest Delay, Copies of Data Packet processed....
I run a few example codes like app-delay tracer, L2ratetracer.
However, i was not able to make sense of the trace file generated.

Any suggestions on how to extract Interest satisfied and Interest Delay
values for a particular simulation?


Thank You,
IHK
