[ndnSIM] Data delivery problem in NDN based Mobile Ad-hoc network (V2V scenario)

[Sonia]

Hi Everyone,

I have a V2V scenario consists of 9 wireless ad-hoc nodes in a grid (no
mobility currently) to check multihop communication. The consumer and
producer node are both at the two extremes of the grid kind of topology. I
and using the simple broadcast strategy similar to this example (
https://github.com/4th-ndn-hackathon/ndnSIM-Mobile-Simulation-Package/blob/8de075fb57cf16358e6c408fac166c3c33f3664c/examples/ndn-v2v-simple.cpp
).
All the Interest packets are delivered to the producer node via multipath
communication and the producer nodes respond with data packets.

However, the problem is that all the Data packets are deemed unsolicited
and being dropped by the intermediate relay nodes.
I also increased the Interest Life time from default 2 sec to 4 and 8 sec
to make it sure that the PIT entries are not expired due to congestion and
long delay in the arrival of data packets. But it didn't work.

Am I missing something?

Your comments would be appreciated.

Thank you

Regards

Sonia
