Can you please help me to configure application correctly

The problem doesn't seems to be the application. Rather it seems to be in the wifi or IP stacks.
We're investigating.

Can you help me to make this scenario work
For your info
I was able to observe the Routing formed by OLSR correctly through Wireshark and IP Table

I am trying to identify the why there is no transmission between N1 and N3?

Because of this: https://gitlab.com/nsnam/ns-3-dev/-/issues/1095
Temporary solution: switch to 802.11n
