Veins LTE simulation Omnet++

[Georgios]

Dear All,

I would like to use the Veins LTE Extension for my simulations.
Can you tell me the versions of Omnet++ INET & Sumo?
Do I need the installation of simuLTE before I continue with the simulations?

[Florian Hagenauer]

Hi,

I am currently using SUMO 0.22.0 and OMNeT++ 4.6.
You can download Veins LTE from here:
https://github.com/floxyz/veins-lte (note that there might be problems
with Windows we are aware of and trying to fix).

Then you need to install it by running "make makefiles" and "make" in
Veins LTE's root directory. Afterwards it should run.

Best,
Florian Hagenauer

Dear Florian,

Thanks for your quick reply.

If I face a problem I will continue this topic.

Dear Florian,

It works!

When I try to run my own scenario, it starts but after 10 sec I get the following error. How can I solve this error?

<!> Error in module (HeterogeneousToLTE) scenario.node[0].heterogeneousToLTE (id=77) at event #66279, t=13.6: IPvXAddressResolver: module `node[5]' not found.

TRAPPING on the exception above, due to a debug-on-errors=true configuration option. Is your debugger ready?

Hi,

two questions which might help to solve that problem:
1. What was the last thing printed before the "Simulation terminated ..."?
2. Did you run the simulation on the Cmdenv or using the Tkenv?

Best,
Florian

Thanks for your help.


1) When I start the simulation, It shows me the road network in SUMO and when gives me the error sumo-gui stops. Now the error is different.
I send you and a printscreen.

<!> Error in module (LtePhyEnb) scenario.eNodeB1.nic.phy (id=26) at event #89321, t=20.102: Error NLOS urban microcell path loss model is valid for 10d<2000 m.

TRAPPING on the exception above, due to a debug-on-errors=true configuration option. Is your debugger ready?

2) I use Tkenv

Hi Georgios

Regarding the first error

1) When I start the simulation, It shows me the road network in SUMO and when gives me the error sumo-gui stops. Now the error is different.
I send you and a printscreen.

 

<!> Error in module (LtePhyEnb) scenario.eNodeB1.nic.phy (id=26) at event #89321, t=20.102: Error NLOS urban microcell path loss model is valid for 10d<2000 m. 

this is probably related to the path loss model that you are using for simuLTE. The "urban microcell" model from ITU in fact, supports only distances, between UE and eNB, below 2000m. You may want to check the maximum distance between the nodes in your network. As an alternative solution, you can change the pathloss model in the config_channel.xml file within your simulation folder (e.g. change it to URBAN_MACROCELL). 

You can find the piece of code that handles those functions in "simulte/src/stack/phy/ChannelModel/LteRealisticChannelModel.cc"

Hope this helps

Best Regards

Hi,

this seems to be a problem related to Tkenv and SimuLTE. As Tkenv
recently started to use the dup() function a lot -- and SimuLTE does not
always implement it correctly -- the Tkenv seems to crash. As a first
workaround until this is fixed I recommend running it on the command
line (Cmdenv) or running Veins LTE in Express mode via the UI.

Sorry for the inconvenience here and I hope that the workaround helps
you for now.

Best,
Florian

Dear Antonio & Florian,

In my simulation scenario the distance between UE and eNB is more than 2000m and I use the URBAN_MACROCELL . What should I do to resolve this problem
Error NLOS urban microcell path loss model is valid for 10d<2000 m ..


In the sample scenario when I add one or more nodes in the route xml file it gives me the other error

<!> Error in module (HeterogeneousToLTE) scenario.node[0].

heterogeneousToLTE (id=77) at event #66279, t=13.6: IPvXAddressResolver: module `node[x]' not found.

Any Help?

How are you exactly adding the new nodes? If I add (for example) a new
vehicle to the file heterogeneous.rou.xml with the line <vehicle id="10"
type="car" route="1" depart="22"/> the simulation runs without a problem.

Best,
Florian

It works but when I run more than one for example 100 nodes (the route file has extra nodes as comments) it doesnt work.
I also changed the simulation time in omnetpp.ini and sumocfg  files and I still have the same error.

IPvXAddressResolver: module `node[x]' not found.

Is there any tutorial or documentation for this Veins Extension for how to solve problems or how to import my own scenario?

Hi Georgios,

I have the same problem while running my simulation in veins-lte heterogeneous scenario (omnet 4.6, sumo0.22, veins-lte 1.2 release)

 <!> Error in module (HeterogeneousToLTE) scenario.node[2].heterogeneousToLTE (id=120) at event #237432, t=9.6: IPvXAddressResolver: module `node[34]' not found.

TRAPPING on the exception above, due to a debug-on-errors=true configuration option. Is your debugger ready?

Could you kindly provide me your solution in order to solve my problem.

I am running my simulation in ./debug > run .
