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

Thu Apr 20 19:44:45 PDT 2017

Hi,

probably you need a pure broadcast strategy and some changes in the NetDeviceTransport class. Please take a look here:

https://github.com/4th-ndn-hackathon/ndnSIM-Mobile-Simulation-Package/commit/d6bce17032111bdf8c170b9c694dced7f0796b14 <https://github.com/4th-ndn-hackathon/ndnSIM-Mobile-Simulation-Package/commit/d6bce17032111bdf8c170b9c694dced7f0796b14>

You might also need to allow NFD to forward a Data packet through the face that it was received:
