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

Fri Apr 21 20:14:55 PDT 2017

Hi,

I have seen issues with a mobile node trying to get associated with an AP, which were resolved with the changes in the NetDeviceTransport that I mentioned before. 

Other than that, you can try to play around with the NetDevice class parameters or send an email to the NS3 mailing list. 

Thanks,

Spyridon (Spyros) Mastorakis
