V2I, V2V and V2X are the communication paths. * V2I is vehicle to infrastructure communication. Vehicles communicate with the Road Side Units(RSU). RSU's provide message routing from one vehicle to other . * V2V is vehicle to vehicle communication. Vehicles directly communicate with each other. * V2X is vehicle to everything . I represents communication with vehicle to everything like cyclists, vehicles, stations etc.. Recently, vehicles communicate by their on board units(OBU) wireless technology. Most of the VANETS now communicate with IEEE 802.11 wireless standart. But to get a better range of communication and low latency communication, it is needed a better medium to communicate. Various wireless communcation technologies can be used like Wlan,LoraWan,etc.. but for low latency cellular communication like 5G will be the best case when applicable. The main aim of VANET is to report events, accident information, traffic information, road conditions, weather reports in the network to provide better safety conditions for the other vehicles in the network.

Vanet communication

The messages in the network must be transmitted with minimum latency and securely.If data is broken or transmitted with delay , there can be hazardous results like vehicle damage and human loss. **Trust models in VANET :** For the data in network to be transmitted accurately, we need to trust the data and the node that generates the data. We need to trust the node and also need to trust the information that is transmitted by the node.
