IEEE 802.11p is like a special language that cars and traffic lights can use to talk to each other. You know how you use words to talk to your friends? Well, cars and traffic lights don't have mouths to use words, so they use IEEE 802.11p to send messages to each other.
Imagine you're driving in your car and there's another car up ahead that suddenly stops. Your car needs to send a message to the other car to tell it to stop too. That's where IEEE 802.11p comes in - it's the language your car uses to "speak" to other cars and traffic lights.
IEEE 802.11p is a way for cars and traffic lights to talk to each other using special radio waves. These waves are like invisible threads connecting all the cars and traffic lights on the road. When your car sends a message, it travels through these threads until it reaches the other car or traffic light.
This is really important because it helps make driving safer. If your car can "talk" to the other cars and traffic lights on the road, it can warn you about things like sudden stops, traffic jams, or accidents up ahead. This gives you more time to react and avoid a crash.
So, IEEE 802.11p is kind of like a secret language that cars and traffic lights use to keep you safe when you're driving. Even if you can't see it, it's always working quietly in the background to make sure you get to your destination safely.
