Kindly provide solution to this problem.

Hi,

I didn't notice such error with vanet.py. Did you make any change on it?

[ibrahimmayar]

No I didnt made any change...!

[ibrahimmayar]

Secondly while running the sumo example the map.sumocfg is not running!

[ramonfontes]

vanet-sumo.py is working too. I didn't find any error with it.

[ibrahimmayar]

The problem is that sumo-gui is not opened and secondly the sumocfg file is not opened

[ibrahimmayar]

I send you request on skype, Kindly accept the request from my skype ID

ibrahimmayar

[ramonfontes]

Can you open sumo-gui via terminal - by typing sudo sumo-gui? Which sumo version do you have?

[ibrahimmayar]

sumo-0.28 version i installed..

[ibrahimmayar]

Where to set the path.. Because when I run sumo-gui from terminal using command sumo-gui, It runs. However, when i run the vanet-sumo.py example, it doesnt find it..

[ramonfontes]

Please try 0.32.

[ibrahimmayar]

okay dear... and how to set path of 0.32..

[ramonfontes]

Path? Which path? There is no need of any path.

[ibrahimmayar]

suppose i download the 0.32 then where should i extract it and what to do then

[ramonfontes]

I suppose this question isn't about Mininet-WiFi. This is about Sumo.

[ibrahimmayar]

yes but to vanet-sumo.py example to run the sumo need to run that example then the mininet-wifi example with execute.. do u have teamviewer.. i can show u the running status

[ibrahimmayar]

I wil install 0.32... can u take screenshot of where sumo is located on ur system... mean path of sumo...

[ramonfontes]

Dear,

Everything you need are SUMO and Mininet-WiFi. Then vanet-sumo.py should work. I have Sumo 0.32 and everything is working as expected. That's why I recommend you to install 0.32.

[ibrahimmayar]

ok.. but u type command which sumo and send me the path which it show.

[ramonfontes]

/usr/bin/sumo - where should it be??

[ibrahimmayar]

Have u installed it by downloading it..

[ibrahimmayar]

my path is usr/local/bin/sumo

[ramonfontes]

Dear,

This isn't a chat. So please be concise. Again, if you have everything installed, vanet-sumo.py should work.

[ibrahimmayar]

Thank you dear for your quick answers.. I appreciate.. I try myself and will let u know..

[ibrahimmayar]

Dear I am thankful Issue resolved

[ibrahimmayar]

I have another question. Can we included our own scenario of sumo within this example.

[ramonfontes]

Yes. To do so, you need to put your map into https://github.com/intrig-unicamp/mininet-wifi/tree/master/mn_wifi/sumo/data and recompile mn-wifi with sudo make install.

[ibrahimmayar]

Dear Ramon Fontes, How can we get the information about the vehicles that are in range of a specific vehicle. For example Vehicle 2 and Vehicle 3 are in range of Vehicle 1. Thanks M.Ibrahim MayarContact #03149110018

[ramonfontes]

Use iw tool.

[ibrahimmayar]

How to use iw tool. For example during running simulation, I want to get the information about the neighbours of a certain Vehicle sy Vehicle 1 and then display this information or send this information to the RSU or other vehicle. I am talking about the code of the paper title ::Cooperative Mobile Edge Computing System for VANET-Based Software Defined Content Delivery. Please guide me accordingly

[ibrahimmayar]

Changing this code:

Sir, I am facing problem, when I am going to execute the python sdcd-experimental.py code at the latest mininet-wifi version 2.6 with sumo-1.18. vanet-sumo.py is executing properly.
