Hello all  ,

I tried to generate name prefixes by configuring consumer and equivalent
producers in an ndn-wifi topology, the delay files (app-delays-trace) and
traces (rate-trace), did not generate any thing .
I don't know if it's a prefix configuration problem or something else.
here is my code. Can someone guides me how can i proceed.

Thanks.
