[ndnSIM] Testing mobility impact on caching (interest packets are not forwarded)

Fri Apr 21 10:12:36 PDT 2017

To be clear my scenario isn't pure Ad-Hoc wireless network it is
infrastructure  one, with wireless mobile nodes connected to Access Points
APs and APs are interconnected by a grid of routers.
