Messages not received by other vehicles because of building

I'm using veins 4.4, OMNeT++ 5.0 and SuMO 0.25, and my project is about intersection traffic control.

I have only one obstacle (building) on my map (by open street map), and my problem is that node 1 is not receiving messages from node 2 and vice versa while in other lanes communication is done perfectly without missing messages.

I think the problem is because of this obstacle. Can anyone help me to get rid of this problem?

Solution

  • The obstacle (which is likely representing a house next to a junction) is behaving as it should: it is obstructing radio communication. There are two ways to approach this: either this is intended, then you would need to design a system that can route data around the house in a multi-hop fashion; or this is unintended, then you would need to remove the building or its effect on radio communication.

    If you do not want to have a building in your simulation, make sure that your simulation does not load the Obstacle Shadowing Model. If you load this model but no obstacles, the simulation will complain.
