I used veins 4a2 and OMNET++ (4.6). I like to know the content of messages exchanged between vehicles in the veins example. I have consulted waveshortmessage.msg, WaveShortMessage_m.cc and WaveShortMessage_m.h but I have not found messages content.
In waveshortmessage.msg, what means this line "string wsmData = "Some Data"" please?
And in TraCIDemp11p.cc, what means "blockedRoadId" declared in sendMessage function?
The demo application that comes with Veins 4.4 (and 4a2 as well) and that is used for the Veins tutorial reacts to messages that contain the name of a road to avoid because a car has stopped there for longer than 10s (and vice versa: the demo application sends a message when a car is stopped for longer than 10s).
The demo application is defined in TraCIDemo11p. It uses a demo message type, WaveShortMessage, as the container to inform other cars about a blocked road. For this, it stores the name of the blocked road (variable blockedRoadId) in the wsmData field of the message.
