Veins VehicleObstacleShadowing Analogue model

[Lantao Li]

Hi guys,

I'm working on my V2V application using Veins and it does run smoothly even with a lot of modifications. However error popped out when trying the VehicleObstacleShadowing analogue model as shown in the attached pictures.

After checking the source code and different versions of the Veins, it seems that all other analogue models all work smoothly except this particular one. This error can trace back to PhyLayer80211p.cc and VehicleObstacleControl.h within Veins, and further into OMNet++ files like csimulation.h and cmodule.h. It seems that the wanted scenario just could not find the path of vehicleObstacles, which is extremely confusing.

Anybody got any ideas on how to resolve this issue? Thanks in advance!

Hello,you must change type id =building in config.xml file according to type id =? in your poly.xml file that belong to your map.and obstacles line =config.xml ...must be found in omnetpp.ini .thanks

Hi, many thanks for the help.

If I understand your answer correctly, those configurations in config.xml are all related to SimpleObstacleShadowing analogue model, which is about static obstacles like buildings (described in the poly.xml). This analogue model is all good in my simulation.

However, the issue I encountered is VehicleObstacleShadowing analogue model, which is about dynamic obstacles (i.e., vehicles themselves as obstacles, and be managed to calculate signal loss when signal passes vehicles in this particular signal's path). in the  VehicleObstacleControl.h file, it shows that this model function does not need any parameters input. And the instance of the scenario simulation just cannot load this module, do you have any clue on that?

It would be so much appreciated if any tips could be given on this issue, since I noticed someone asked the same question on Stack Overflow and no answer is given yet.

Anyway, thanks again for your answer.

Resolved by myself already. Forgot about checking those .ned files.
