Seeking guidance on integrating Veins 5.3.1 for 5G NR V2X simulation

[kouamdo]

Environment

OMNeT++: 6.3.0

Simu5G: Master branch (cloned ~Dec 11, 2024)

INET: 4.5.0 (Also tested with 4.4.0)

Veins: 5.3.1

SUMO: 1.18.0 (TraCI API v20)

OS: Linux (headless)

Issue Description

When attempting to run the cars emulation V2X inside 5G NR configuration in the simulations/nr/cars example to simulate 5G NR V2X sidelink communications, the simulation fails to start due to a NED file loading error for CarUeNr.ned. The OMNeT++ kernel searches for this file in incorrect paths.

### Steps to Reproduce

Successfully compile all frameworks (OMNeT++, INET, Simu5G, Veins).

Navigate to the example: cd /path/to/Simu5G/simulations/nr/cars.

Execute the run script:

opp_run -l out/gcc-release/src/simu5g -l ../inet4.5/out/gcc-release/src/INET -l ../veins-veins-5.3.1/out/gcc-release/src/veins -n src:simulations:../inet4.5/src:../veins-veins-5.3.1/src/veins -u Cmdenv -f simulations/nr/cars/omnetpp.ini -c VoIP-D2D --sim-time-limit=200s

Observed Error

<!> Error: Could not load NED sources from '/.../Simu5G/src': Cannot canonicalize 'CarUeNr.ned': realpath() failed: No such file or directory

Troubleshooting Performed

Found duplicate CarUeNr.ned files in:

simulations/nr/sumotest/ (Fixed an incorrect import statement here).

simulations/nr/cars/ (Removed).

src/simu5g/nodes/nr/ (Removed, suspected erroneous location).

Cleared build cache (make clean) and .neddy files.

A manual opp_run command bypassed the initial NED error but led to a separate library symbol error (undefined symbol:
_ZTIN4inet9ieee8021112Ieee80211MibE), indicating a potential INET version mismatch.

### Key Questions

Project Structure: Is the CarUeNr.ned file expected to reside in src/simu5g/nodes/nr/? The run script seems to require it there.

Veins Compatibility: Is Veins 5.3.1 officially supported for this example, or is only Veins 5.2 tested? Are specific configuration steps needed?

Recommended Workflow: Should we use the provided ./run script or a manual opp_run command from the project root?

INET Version: Which INET version is compatible with the current master branch? Is INET 4.4 the tested version?

Supporting Files
The unmodified omnetpp.ini, Highway.ned, and heterogeneous.launchd.xml from simulations/nr/cars/ are used.

Thank you for your assistance. Clarification on the expected structure and workflow will greatly aid in using this V2X example.

Why are you using Simu5G master from some past date (a few weeks before the 1.3.0 release it seems), why not a released version? Generally speaking, commits between releases represent a development snapshot of uncertain state.

As a side note: For installation, have you tried using opp_env? The following command will install these projects without needing manual intervention:

opp_env install veins-5.3.1 simu5g-1.3.0 inet-4.5.4 omnetpp-6.3.0

To list what other combinations have been supported, see

opp_env list --expand inet simu5g veins

To address some of your questions:

• INET Version: Testing is done with inet-4.5.4
• Recommended Workflow: just "simu5g" or "simu5g_dbg" run from the specific simulation's folder; those are shell scripts under simu5g/bin (which setenv puts into the PATH)

As for your other questions: I haven't looked at Simu5G-Veins integration more closely yet, I'll try to find time for that in the next days.

a tip: the car/mobility feature in Simu5G is disabled by default. YOu must enable it first:

opp_featuretool enable Simu5G_Cars

then rebuild Simu5G (make makefiles; make)

@rhornig

that is the result , i'm rigth ? is it all about to test cars simulations inside 5G network?

i have tried this by using veins and simu5g :

inside one terminal :

omnetpp-6.3.0+inet-4.5.4+veins-5.3.1:/home/ledoux/v2x_nr/veins-5.3.1# bin/veins_launchd -vv -c /nix/store/gp4hbfbrxg4zzjs7g3nl7vy0rw4jmm2y-sumo-1.22.0/bin/sumo
Logging to /tmp/nix-shell.OModAm/sumo-launchd.log
Listening on port 9999

and inside another one :

cd /home/ledoux/v2x_nr/simu5g-1.3.0/veins_inet
opp_env shell simu5g-1.3.0
./run -u Cmdenv

that is one of the issue that i'm facing

i think , and hopely resolve the problem concerning link between simu5G and veins , now i'm facing this issue :
