[ndnSIM] Cache hits: identifying the originator

Dear ndnSIM list members,
I am working in a wireless scenario with N consumers and M producers, connected via intermediate nodes (see example below)
O -- O -- O -- O ... O -- O
/ Rtr-1 Rtr-n Producer 1
Consumer 1 and 2 issue Interest requests via ConsumerCbr application (same namespace, e.g. /prefix/ ). As the number of routers increase, the link has more collisions and the Interest/Data packets get lost, generating more retransmissions and cache hits.
Is there a way to know which node originated the cache hit? Also, is there a way to know if a cache hit was originated by a retransmission or by a first-time Interest request?
I looked at "Finding Id of interest sending node<http://www.lists.cs.ucla.edu/pipermail/ndnsim/2016-March/002455.html>" but that solution seems to not fit in this scenario.
Thanks for your help,
