[ndnSIM] ndnSIM - Producer problem

[Marzieh Babaeianjelodar]

Dear All,

Thank you for your responses.

yes, I have four nodes 0, 1, 2, 3.

When I run the NS_LOG and the nodes are far away (200) from each other, only node 0 sends interests to node 1 and nothing else happens, In this case interest does not reach the producer and my question is why?
node 1 does not rebroadcast to node 2 and node 2 does not rebroadcast to node 3.

But, when I move them closer (25 distant) from each other the interest reaches the producer and producer can reply.

I am using the multicast strategy here. 

Best Regards,
Marzieh

I want the nodes to only reach the next neighbor hop and not the other hops so I spaced them out. The problem is that when my producer node (node 3) is farther away from consumer node it does not send back the interest
