Error setting up IEEE802.11p in mininet-wifi #437

Closed alamfaisal654 closed 2 years ago

I tried setting up the IEEE802.11p with the details given at the home page of mininet-wifi. But it is still not working for me.

These are the steps that I tried:

  1. Installed python-m2crypto, python-m3crypto and future.
  2. Installed regdb . This was succesful.
  3. Installed libgcrypt11-dev.
  4. Installed crda as given on the web page.

Troubleshoot steps:

  1. wifi@wifi-virtualbox:~/Desktop/SumoFiles$ sudo /sbin/regdbdump /lib/crda/regulatory.bin | grep -i ocb [sudo] password for wifi: country 00: invalid (5850.000 - 5925.000 @ 20.000), (20.00), NO-CCK, OCB-ONLY The above step was succesful as given on the web page.

  2. iw reg set DE

  3. iw reg get wifi@wifi-virtualbox:~/Desktop/SumoFiles$ iw reg get global
    country 00: DFS-UNSET
    (2402 - 2472 @ 40), (N/A, 20), (N/A)
    (2457 - 2482 @ 40), (N/A, 20), (N/A), NO-IR
    (2474 - 2494 @ 20), (N/A, 20), (N/A), NO-IR
    (5170 - 5250 @ 80), (N/A, 20), (N/A), NO-IR
    (5735 - 5835 @ 80), (N/A, 20), (N/A), NO-IR
    (57240 - 63720 @ 2160), (N/A, 0), (N/A)

  4. I had a look at IMPLEMENTATION AND EXPERIMENTAL EVALUATION OF COOPERATIVE AWARENESS BASIC SERVICE FOR V2X COMMUNICATIONS

  5. lshw -C network *-network:6 description: Wireless interface physical id: 7 logical name: ap1-wlan1 serial: 00:00:00:00:00:01 capabilities: ethernet physical wireless configuration: broadcast=yes driver=mac80211_hwsim driverversion=5.4.0-100-generic firmware=N/A link=no multicast=yes wireless=IEEE 802.11 WARNING: output may be incomplete or inaccurate, you should run this program as super-user.

I understand that 5.9GHz is CRDA is not properly enabled here, but how do I enable it. I am using the VM provided on the mininet-wifi web page. I followed all the laid down steps . I also tried to google and find what could be the issue but none seems to be working. I presume someone from your team would have setup IEEE802.11p on this VM. Can you help with troubleshooting steps as to what could have gone wrong. The laid down steps do not work. Attaching the code file

Honestly, I think this is not an error about setting up IEEE802.11p in mininet-wifi but an issue with your system. You cannot even make physical devices work with 11p if you don't enable 5.9GH in the regulatory domain. Moreover, it seems that you have Kernel 5.4 and not later ones.

Anyway, if the first step is working I'd suggest you replace all the regulatory.bin files your system have by that one generated by you. This is the first and simple next step I'd try.. I also suggest you disable Network Manager.
