using customized sumo files

[daniel crown]

hi,

I want to use my sumo net, rou and config files where I have simple 3 lane road with 500m. I have saved the corresponded these files to mininet-wifi/mn_wifi/sumo/data where newyork files are also exist. however the simulation does not run, I see no error but the neither sumo gui runs any vehicles nor mininet wifi nodes are moving. I see my customized network and new york network are visible in sumo-gui. Although as I told I updated the path in mininet-wifi sumo-vanet.py script with my network.

I have tested the sumo configuration without mininet the network runs individually without an issue.

thank you.

[Ramon Fontes]

It’s a bit difficult to follow what’s going on, especially since there’s no error message being emitted. Could you please share your SUMO files and explain the steps to reproduce the behavior you mentioned is working? That would help a lot in understanding the issue.

[daniel crown]

Hi, PLease find the attached sumo files.

I have 3 lane 500m road for lane change prediction setup. I want to test with first simple test environment like this, normally I will extend it.

I have stored these file in mininet-wifi/mn_wifi/sumo/data where newyork default files exist.

I first did not change anything in vanet-sumo.py but I will change the AP numbers where I test with newyork file without any issue when I change to access point to 1.  But again when I use my costumized sumo files the simulations does not work here as well.

Thank you. Regards.

There is no definition for TraCI (Traffic Control Interface) in your sumocfg. Please try to replicate the definitions of our sumocfg.

[daniel crown]

***Starting server on port 8813 ***

when I update the sumocfg like your I see in sumo-gui above only nothing comes.

Your code works. The problem was that you created vehicles with non-integer IDs. You have to rename them to

<vehicle id="1" type="autonomous" route="r0" depart="0" departLane="1" departPos="0"/>
<vehicle id="2" type="human" route="r0" depart="1" departLane="1" departPos="20"/>
<vehicle id="3" type="autonomous" route="r0" depart="2" departLane="1" departPos="40"/>

[Ramon Fontes]

By the way, if I were you I'd use config_file param (https://github.com/intrig-unicamp/mininet-wifi/blob/master/examples/vanet-sumo.py#L65) instead of moving sumo files to /data.

[daniel crown]

I have updated sumocfg and net file with id integer values as well. but simulation from command does not work.

but when I upload manually net file to sumo-gui it shows attached file notification.

about the config_file parametes, I did not understand what should I do here. because I do following config_file='/home/ubuntu20/mininet-wifi/mn_wifi/sumo/data/test1.sumocfg', It is weird now that with vanet-sumo.py with this files sumo vehicles moves but mininet wifi nodes does not appears and I dont see any move as attached.

Please see attached screencast. As I said your code works - Honestly, I don't know what is going wrong there.

ps. your recent sumocfg file had a definition for poly file but you don't have one. ;/

[daniel crown]

thank you for your share, I do same and attached it seems it is working, but the nodes in mininet wifi are not moving? I see 6 AP that are statics but the nodes (vehicles) are not showing. i want to ping and chech the v2v and v2i is working fine or not.

about poly, I wonder do I need that or not, I try to not include that, that is why I removed in sumo.cfg file now as well. because when I add that I see on top of 3 lane  my costumized road the new-york net setup as well.

also when I do config_file= 'test1.sumocfg' like you I see below error in sumo

Error: Could not access configuration 'test1.sumocfg'.
Quitting (on error).

However I added full path config_file='/home/ubuntu20/mininet-wifi/mn_wifi/sumo/data/test1.sumocfg' and it worked like your test. It is weird.

Your code answers both the questions:

> but the nodes in mininet wifi are not moving?

They are moving. The min_x of the graph is set to >2000 while vehicles are located ~200.

> Error: Could not access configuration 'test1.sumocfg'.

Is there a test1.sumocfg in the same directory of your code?

[daniel crown]

 there is a 1 test1.sumocfg in the directory of the code.

for node moves: I wonder how you say the vehicles are located ~200? it is from net files or what? I am curious how you identify that? so  when I reduce the value min_x of the graph to around 200. Should I change from python script is better or in sumo files to these values if it is in sumo files?

Is that ok to do:

 net.telemetry(nodes=nodes, data_type='position',
                  min_x=220, min_y=280,
                  max_x=320, max_y=390)

 and   

    kwargs = {'ssid': 'vanet-ssid', 'mode': 'g', 'passwd': '123456789a',
              'encrypt': 'wpa2', 'failMode': 'standalone', 'datapath': 'user'}
    e1 = net.addAccessPoint('e1', mac='00:00:00:11:00:01', channel='1',
                            position='260,350,0', **kwargs)
    e2 = net.addAccessPoint('e2', mac='00:00:00:11:00:02', channel='6',
                            position='280,350,0', **kwargs)
    e3 = net.addAccessPoint('e3', mac='00:00:00:11:00:03', channel='11',
                            position='300,350,0', **kwargs)
    e4 = net.addAccessPoint('e4', mac='00:00:00:11:00:04', channel='1',
                            position='260,330,0', **kwargs)
    e5 = net.addAccessPoint('e5', mac='00:00:00:11:00:05', channel='6',
                            position='280,330,0', **kwargs)
    e6 = net.addAccessPoint('e6', mac='00:00:00:11:00:06', channel='11',

If there is a sumocfg file you don't have some permission to read it. Please double check your environment.

From net and you can confirm the position in mn-wifi with node.position.

[daniel crown]

thank you, now I suppose after adjusting net file it seems that is visible as well as attached. 

About permissions I think thats look OK, is it not?

Dear,

The error message says: "Error: Could not access configuration 'test1.sumocfg'." This means that the file doesn't exist or there is no permission to access it.

By the way, please close the issue on github with the solution you have adopted.

[daniel crown]

okay thank but I wonder if we config_file='test1.sumocfg', directly, instead    config_file='/home/ubuntu20/mininet-wifi/mn_wifi/sumo/data/test1.sumocfg', where my config file exist, what is the difference?

how config_file='test1.sumocfg' understands the file path exactly?

I set permission as following: sudo chmod 666 /home/ubuntu20/mininet-wifi/mn_wifi/sumo/data/test1.sumocfg is that ok?

Honestly, I didn't get your point.

I didn't get this either. What do you mean with connectivity tests?

>  Also I want to be sure that for V2V and V2I which one is used for which IEEE 802.11p and IEEE.802.11g?

Which ones did you set as master and ITS modes?

[daniel crown]

the default script has 6 AP and linked each other, my point is I want to have 1 AP.

the default script have from loop for car in net.cars ITSLINK and from loop of AP 'mode': 'g'.

I am confused with these? this means V2V is itslink and V2I is ieee802.11g connected right?

The connectivity test means I try to follow this link you provided earlier https://github.com/ramonfontes/mn-wifi-ebook/blob/main/expert.md#vehicular-ad-hoc-networks    (e.g car4 ping -c1 192.168.1.6 which use one of its interface for V2V it this over its link?)

if car4 ping -c1 192.168.0.6 we do this which means another interface is used for V2I and it is through itslink?

The interface a node uses to transmit packets depends on the destination address, the default gateway, and the subnet configuration. You can easily track this by analyzing the packets.

[daniel crown]

Hi,

in vanet-sumo.py there is and car linked with ITSLINK which is channel 181  (DSRC) communication protocol is used. and  you are pinging vehicle number 3 and 5 (v2v) using car4 ping 192.168.1.6

my point is for the V2I how we do test it is working or not?

and each access point has mode g is this IEEE 802.11g? this part is mesh mode network right? the 802.11g is used to communicate for access point each other not for with vehicle to access point (V2I) ?

lastly, since you have 6 access point linked each other, I want to use only 1 AP to communicate with vehicles. how to configure that (Reduce AP to 1) ?

Try connecting two or more vehicles to the base station (BS) and run a ping between them ;/

> and each access point has mode g is this IEEE 802.11g

Yes, and I recommend reading the Mininet-WiFi book for a deeper understanding of how Mininet-WiFi works.

> the 802.11g is used to communicate for access point each other not for with vehicle to access point (V2I) ?

Which protocol can be used for AP-AP wireless communication? This will answer your question. There is no wireless communication among APs in vanet-sumo.py.

> lastly, since you have 6 access point linked each other, I want to use only 1 AP to communicate with vehicles. how to configure that (Reduce AP to 1) ?

If you want to use 1 you have to reduce to 1. Is this really a question?

[daniel crown]

Hi Ramon,

Thank you for your all returns and recommendations like book reading. But I have still little bit unclearity about the setup and communication protocol use in default 6 AP setup. I am unclear with communication of V2V and V2I.

There is 2 interface that each assigned for v2v or v2i respectively. 

(V2V) car1 ping -c1 192.168.1.2 (Car1-car2) is direct communication between vehicle is done through IEEE 802.11p right?

(V2I) car1 ping -c1 192.168.0.2 which is vehicles (Car1-car2) are communicating through AP with IEEE 802.11g right?

I used my personalized setup as 1 AP and multiple cars as node. I see packets are %100 lost (destination is unreachable) in  car1 ping -c1 192.168.1.2 but in case car1 ping -c1 192.168.0.2 packets are transmitted and received without loss. 

also can we say that when the mininet wifi plot circles are in range of vehicles with color that is validation of the vehicles are in range of AP?

You should check the python version or even CRDA and REGDB you have. Unfortunately, I'm unable to provide instructions on how to compile CRDA and REGDB.

[daniel crown]

I have python 3 version. that is why I ask you actually because when I compile the  CRDA and REGDB I see that the python scripts as python2 version although I have start with using sudo apt install python3-m2crypto # python3

Installing python3-m2crypto and future for Python 3 doesn't resolve these issues because the scripts are written for Python 2, leading to syntax and function errors when run with Python 3. I assume the problem this but I donot know how to fix it?

If the Python version is causing issues, why not simply use the supported version? Please keep in mind that this mailing list is intended for Mininet-WiFi-related questions ONLY!

It appears that more time should be dedicated to understanding the tools and technologies you're working with. For instance, initially you didn't follow the instructions in vanet-sumo.py and spent two weeks trying to set up a communication that wasn't possible.

Now, you're repeatedly messaging about Python version compatibility. I’ve already clarified that Mininet-WiFi supports both Python 2 and 3. However, it’s not my responsibility to tell you which version to use to make third-party tools work. That's something you need to determine based on the requirements of those tools.

[daniel crown]

hi,

thank you for your reply. I actually spend much time to understand this tools but I face difficulties about them sorry for reaching you many times. 

I do not know it was correct way to do so since  python-m2crypto did not work and I tried

python3-m2crypto and that brings python2 written issue of some files as db2pin.py and dbparse.py. 
I could not figure out the issue that is why want to know there is similar problem or not. now i updated these files manually to python4 and I reach some point.

as I see in crda werror issue I did "remove Werror from the Makefile of crda if you have problems with keys-gcrypt.c." now. do you think it is okay that the setup is fine based on attachement?

This occurs in only two situations:

1. Mininet-WiFi has not been installed successfully. 

2. Mininet-WiFi is not installed in the Python version you are currently using.

Come on, the mn_wifi.link module exists: https://github.com/intrig-unicamp/mininet-wifi/blob/master/mn_wifi/link.py. :( If it exists and your system cannot find it you have to guarantee that it is correctly installed.

[daniel crown]

By saying “Mininet-WiFi has not been installed successfully” is weird that the installation instructions has only 4 line commands straight forward I copy and paste and run from the instructions ebook. 

“Mininet-WiFi is not installed in the Python” means what I don’t understand? Ubuntu 16.04 with python 2 is using as system.

no, I mean that I check the link since there error is about missing module called " mn_wifi.link module". I could not see in the link.py this module that is why I want to be sure.

as I actually use ubuntu 20.04 for vanet-sumo.py test before, we face issue with 802.11p setup, therefore I want to recheck the https://mininet-wifi.github.io/80211p/ will be working in lower version of ubuntu since the team of  CTU-IIG/802.11p-wireless-regdb recommend me to use lower linux-ubuntu version due to that is  quite old project and making it run on newer Linux might be challenging. I just want to understand the issues simply. because in ubuntu 16.04 the  80211p setup is download without an issue, but for 20.04 it is not working. do you get my point? if at least I can use mininet in 16.04, I can test vanet-sumo.py.   I just want to learn this tools for my project.

Mininet-WiFi works since Ubuntu 16.04 and 802.11p up to Ubuntu 24.04, at least.

It is your luck Daniel that Ramon is answering your level 0 answers. 80211 works when i was in my Master's degree in 2019. Please check your VM or change it.
