Any one uses Veins-LTE please？

[wx1...@my.bristol.ac.uk]

Hi,

Does Veins-LTE work properly ? I have a lot of errors after importing the VEINS INET Simulte. I imported the 3 together, ticked With INET Framework for Veins and build them all. Then I got errors like showing in the the picture attached.

Could anyone please tell me if I missed some important step or I just need to correct those errors one by one?

Thank you so much for your help.

[wx1...@my.bristol.ac.uk]

Fixed by changing the OMNeT++ version from 5.0 to 4.6.

New problem now is when I run the simulation, error message appeared, saying that :

Loading configuration... Error: tcpip::Socket::accept() Unable to create listening socket: Address already in use
Quitting (on error).
done.

Also message in the attached picture. Could anyone please tell me how to solve this problem?

Thank you soo much in advance.

Hi,

could you please send the whole error message as text and not as a screenshot. Currently the screenshot hides some of the actual content.

Hi thanks a lot for your reply.

I'm now using sumo-0.25.0 and Omnet++ 4.6 and veins-lte 1.3. I imported all the 3 files into OMNET, deleted a repeat definition of a parameter(I think that's not correct to re-define it), tick the choice with inet, built all and run the ini file in example folder. Then I got error message on console as shown in the text below.

Many thanks for your help.

Hi Wanru Xie,

the error is fixed in the latest version of Veins LTE which can be downloaded on veins-lte.car2x.org.

Beside that, I recommend running Veins LTE via Cmdenv and not via Tkenv.

Hi Florian,

Thanks for your reply. Which error did you said been fixed? I just downloaded the Veins-lte-1..3 from the web site you mentioned in the last email. Errors still exists. 1. The ''debug'' is already defined.

When I deleted the sentence to re-define ''debug'', run it, after a little while, the simulation stops, errors appears as follows:

Hi Wanru Xie,

how did you run Veins LTE? Using the OMNeT++ GUI?
If so, there is a bug inherited from SimuLTE which currently crashes Veins LTE in case you run it via the GUI. To avoid this bug, please run it either in Express mode or via the command line (i.e., Cmdenv).

Florian Hagenauer

Hi Florian,

Thanks a lot for the information. I was using OMNet++ GUI. I just tried Cmdenv and Express mode, they both work well but SUMO doesn't appear when the simulation was running. Is this right? Do I need to open the sumo-launchd.py? Can I view SUMO GUI in this case?

Best regards,

Wanru

Hi Wanru Xie,

you don’t need sumo-launchd.py, just modify the commandLine parameter in your omnetpp.ini as follows:

*.manager.commandLine = “sumo-gui --remote-port $port --seed $seed --configuration-file $configFile”
instead of
*.manager.commandLine = "sumo --remote-port $port --seed $seed --configuration-file $configFile”

Hi Florian,

I have been reading Veins-LTE related paper and the frame. Could you please help me with the following questions:

1. Is the connection via 11p or LTE random? I saw the randomness from  ExampleDecisionMaker.cc.

2. How are the messages scheduled? How can I modify the content or size of messages?

3. I enabled sendBeacons and sendData in .ini file. However, I CAN'T see any difference from console. How can I check the communication results of beacons and data?
*.node[*].appl.sendBeacons = true
*.node[*].appl.dataOnSch = true
*.node[*].appl.sendData = true

Thanks a lot for your kind help!

Best Regards

[Florian Hagenauer]

In the example it is random, but you can implement any type you want in your own DecisionMaker.

Yes, you can modify the contents. How to create your own messages can be found in the OMNeT++ Manual [1].
Regarding the scheduling, you can send messages on your own schedule via the application layer - and also the IEEE 802.11p stack as well as the LTE stack perform some scheduling according to their respective standards.

These are some remants from the Veins example, they currently do not affect the heterogeneous example.

hi, florian

may i ask you,

1. to stop the debug error, can i do "//" on the " bool debug = default(false); " on of file DecisionMaker?
2. you said running on cmdenv, is the runnung same mean like also installing on cmd?

please help me

[Florian Hagenauer]

Hi,

1. Yes, you can change the parameters in the different files. But this
won't stop the error.
2. On the Veins LTE Website [1] you can find two ways to install Veins
LTE. Running Veins LTE and compiling it are two different steps and are
(usually) independent of each other.

Best regards,
Florian

hi, florian,

1. which is better way for installation, import with IDE or terminal?
2. if i run via cmdenv, how to record the simulation result from omnet++?
3. could i still controlling my simulation from omnet++ if i running it from cmdenv?

best regards

[Florian Hagenauer]

Hi,

1. Both should work well, but I recommend using the command line.
2. The simulation results are recorded independent of cmdenv or Tkenv, so no difference here.
3. The simulation is still running using OMNeT++. Sadly you can’t start/stop/pause the simulation via any OMNeT++ GUI if run via the command line. But, if you use sumo-gui, you can use this to stop/start/pause the simulation.

Best regards,
Florian Hagenauer

Dear mr florian, can you help me how to measure throughput, end to end delay and packet loss on my simulation using veins-lte, i use inet.util.ThruputMeter but the result is different while throughput calculate by ned.Dataratechannel.

thank yo su much

[ferra adelinna]

hello mr florian, let me ask you, in heterogeneos example, i'd like to make simulation using lte broadcast to node. can you help me how to find the node's position and sourceaddress in simpleserverapp.cc.

thankyou so much.

[ferra adelinna]

dear mr alfonso , im using enb for broadcast message to vehicles can you tell me how to find the position and ip of the vehicles . thank you. please help me.

[ferra adelinna]

really sorry bout wrong to say your name. i mean mr florian. thankyou

[Juan j]

Dear Ferra.

Maybe you reached measure throughput, end to end delay and packet loss on my simulation using veins-lte? I want to do the same.. please help me.

Thanks.

[ferra adelinna]

Hello juan, you can measure end to end delay by inserting the codes in application modul. End to end delay is measurement of arrived time - sending time of packets.

For througput you can use automatically channel throughput from omnet++ library.

Dear Ferra,

Thank you for you response. I'm sorry but i don't know how insert the codes in application module. Could you help me with that please, Or if is possible that you share with me your omnet.ini file to review your configuration please.

Thanks.!
