The code works perfectly fine for 10 stations. When I try to create more than 10 stations in the above code, I get the following error. It is very strange to see this error. I hope the error is related to positioning of vehicle or network interface. I checked in issues and mininet-wifi conversations as well but of no use. Can you please help me resolve this ?

You have set a mobility model and static positioning in the same scenario. What do you actually want to do?

Thank you for the reply. Sir, I want to move the vehicles from one point to another. That's it. What is the issue ? Can you please correct which line of code has the issue ? One more question is you mentioned that I set a mobility model and static positioning in the same scenario. In that case, the mobility or code works fine with 10 vehicles. Issue arises when I create 11th vehicle. May I know my mistake ?

Sir, I corrected the issue. I actually gave same MAC address for both sta1 and sta11. So, the position is unclear in the code. I corrected the MAC addresses. It works fine now. Thank you so much Sir.
