[ndnSIM] Integration of ndn in LTE networks

[Renato Cavalcante]

Hi,

My scenario is:
     __________               ---------                   ___________
    | enbNodes | -----------| SGW |---------------| remote host |
    -----------------               ---------
-------------------
      _______
     |ueNodes|
     -------------

The problem happen in the wireless network (between ueNodes and enbNodes).

When the ueNodes is the consumer and enbNodes is the producer, the Interest
packets has been send, but without Data packets received.

When the ueNodes is the producer happen the error bellow:


*> Interest for 0*
*Trying to add 0 with +0.0ns. already 0 items*
*assert failed. cond="protocolNumber == Ipv4L3Protocol::PROT_NUMBER",
msg="unsupported protocol 30583, only IPv4 is supported",
file=../src/lte/model/lte-enb-net-device.cc, line=347*
*terminate called without an active exception*


What class and method should I customize?


I wait for your help.
Thanks in advance
