Hello, everyone!

I need your help.
I am using SimuLTE and Veins to simulate a vehicular network with D2D communication.
link: http://simulte.com/add_veins.html

I want send a message (application module) from car to eNodeB, but simulator says that destination ip address has left the simulation.

How I can do it?

As I understand it, only static peering is supported in SimuLTE. Therefore, once you specify *.ueD2DTx[0].nic.d2dPeerAddresses= "ueD2DRx[0]", ueD2DTx will only see ueD2dRx. You'll have to modify the LTE Nic stack to achieve dynamic peering.

Hi,

the current version of SimuLTE does not allow the communication between an application on the UE and an application at the eNodeB.
You can setup a connection with a remote host outside the LTE network, possibly coexisting with the D2D connection with another UE. 
SimuLTE also allows you to dynamically switch the D2D communication from the direct link to the traditional infrastructure path and vice versa, according to either a best-CQI policy or your own policy. You can find some information about this in this paper: 

G. Nardini, A. Virdis, G. Stea, "Simulating device-to-device communications in OMNeT++ with SimuLTE: scenarios and configurations", OMNeT++ Community Summit 2016, Brno, CZ, September 15-16, 2016

Best regards.
Giovanni

Thank you for your responses!

I tried sending UE message to a server, but it did not work.
Should I enable D2D communication on the server? In this case the enodeb will not be the nexthop of the UE?

Would it be possible to transmit from eNodeB to the vehicle and vice versa with the modeselection?
I understood that eNodeB will only retransmit messages exchanged between UEs.
