Error ([Errno 111] Connection refused) in veins (sumo-launchd.py)

Question

i want to use veins, to co-simulate between OMNeT++ network simulator and SUMO road traffic simulator.

Veins has sumo-launchd daemon (written in Python), that is designed to run in the background, listening for incoming requests. On each incoming connection, it receives the simulation setup in XML format, then launches a separate instance of SUMO and proxies requests between OMNeT++ and SUMO.

When i run sumo-launchd.py (after opening OMNet++ and start simulation) in the terminal, i get the following issue, which i believe is Python related.

bluemix@blueMix:~/SUMO/veins-2.1/examples/veins$ python /home/bluemix/SUMO/veins-2.1/sumo-launchd.py -vv -c /home/bluemix/SUMO/sumo-0.19.0/bin/sumo

and the information from OMNeT++ console:

<!> Error in module (TraCIScenarioManagerLaunchd) scenario.manager (id=6) at event #1, t=0: Model error: Connection to TraCI server lost. Check your server's log. Error message: 104: Connection reset by peer.

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

Simulation terminated with exit code: 2

I googled (1, 2) the problem, but not exactly the same as mine. Thanks in advance.

Was it helpful?

Solution 2

This is the reply from the veins owner (Christoph Sommer):

https://github.com/sommer/mixim-sommer/archive/b47beb0c.zip

This one should work for all current versions of SUMO. Note that it has not received extensive testing yet, so please let me know any problems.

Best,

Christoph

OTHER TIPS

you need to launch the sumo by using the following line from terminal:

sumo-launchd.py -vv -c sumo-gui

and the run the omnetpp.ini file from omnet++
