Secure two-way communication in MANET's using AES and RSA algorithms with HC-12 module

In the developing nations, road accidents are the significant reasons for death. For instance, if we look at the main 10 risky roads in the world, we can see that every one of them is a mountainous road. In the mountain roads, there will be tight bends and the roads will be restricted. In these sorts of circumstances, the driver of a vehicle can…
