[ndnSIM] Interest loop problem in VNDN (v2v scenario)

[Sonia]

Hi,
Thanks, but will the DeadNonce list not prevent it? The PIT entry is
deleted but duplicate nonce could be found in DeadNonce list. Isn't it?

For my 2nd concern, I have made a scenario of 50 ad-hoc nodes moving in a
certain direction. I have added Ad-hoc netdevice transport as done in the
example (
https://github.com/4th-ndn-hackathon/ndnSIM-Mobile-Simulation-Package/blob/master/examples/ndn-v2v-simple.cpp
)

Is that all to make an ad-hoc v2v scenario? or please guide me if I am
missing something?

Thank you
