Hi Xuan,

If the losses happen in the network layer due to buffer overflows (most likely in your case), you can use L2Tracer (http://ndnsim.net/metric.html) that was actually implemented to trace packet drop specifically (and for now supports only that).

I use GlobalRoutingHelper to add prefix origin to the nodes that are generating interests.  I have used BestRoute as the forwarding strategy.
