You could use the global node id assigned by NS3:

Simulator::GetContext()

Take a look here:

The thing you are doing right now could lead to some privilege conflicts with the managers of NFD. That might be the reason you get this timeout.

My scenario is, after receiving data(onReceiveData()) with name "/data/R/00" from face i, I want to add a route manually (using fibhelper) for prefix "data/D/00" with face i as the faceid to reach the nexthop. I can use the Addroute() function but it is not possible to get the node(GetNode()) who is currently accessing the forwarder.
