Is it probably the problem with the RangeModel?. I have also calculated the node's position to each other and make sure there will always be nodes within range of a node, so the RangePropagationLossModel should also work

Yes, it can be related to the loss model.

An app merely generates Interests (consumer) and responds to Interests with data (producer). Forwarding code should be in the forwarding strategy or directly in the forwarding pipelines (forwarder.cpp file) of NFD.
