[ndnSIM] Problem with receiving data in my 3 noded scenario

Hi, I wanted to add that,

I also tried the code in this V2V scenario, but I get the same results that I mentioned in the previous email. After it reaches to the producer, the previous node does not get the data back.

Best Regards,

My nodes are far from each other with the same distance from each other. The nodes are just one hop reachable, so for sending interest from node 0 to node 2, node 1 has to be used in the middle.

I used Constant Speed Propagation Delay Model and used “Three Log Distance Propagation Delay Model” and “Nakagami Propagation Loss Model”. I used “Yans Wifi Phy Helper” for creating the wifi channel. I used “Nqos Wifi Mac helper” for configuring the Mac model.

When I enable the log I can see that my interest goes through from node 0 to node 1, and from node 1 to node 2, and node 2 gets satisfied, and node 2 sends the data back to node 1, but node 1 never receives the data. Node 1 and 0 are unsatisfied. I was wondering why node 1 is not getting the data back?
