vanet sumo mininet wifi
daniel crown
Hi,
In the vanet sumo script cars have two WLANs
Interface | Technology | Purpose
wlan0 | 802.11g Wi‑Fi | V2I (car ↔ AP)
wlan1 | 802.11p DSRC | V2V (car ↔ car)
which means only V2V is supportive for 802.11p, can we make V2I 802.11p as well? I want to analyze the performance of V2I 802.11p.
You say "I may add an AP and set the link to ITSLink."
But I see
I did like following:
#!/usr/bin/env python
"""Sample file for VANET
***Requirements***:
Kernel version: 5.8+ (due to the 802.11p support)
sumo 1.5.0 or higher
sumo-gui
Please consider reading https://mininet-wifi.github.io/80211p/ for 802.11p support
"""
