Wir simulate VANET connection using NS2 and several protocols such as ADV, DSDV and DSR and then compare their performance using PDR (PDR). High PDR protocols are regarded as efficient and dependable. We're utilising packet encryption and decryption in our project to keep communications between cars safe. Both vehicles will send and receive encrypted signals about the distance and other traffic conditions while they are in close proximity, and these messages will be decoded when they are received. The VANET sensor cannot be hacked by anyone who is able to decipher the messages that are exchanged in the network. Our SUMO simulator is used to produce traffic mobility traces, which are then used to calculate protocol performance in NS2. The NS2 protocol will send alerts when a car arrives within a certain distance of another vehicle in this trail. When two vehicles get within a certain distance of one another, they exchange encrypted and decrypted distance messages, and one of the vehicles will halt and resume motion when the road is clear. I'll present the implementation in video so you can see the results for yourself. I'll plot the PDR performance of the DSDV, AODV, and DSR protocols after they've all been run
