One of the easiest ways to understand ad hoc networks is through the “string-phone” analogy. It’s what most kids have played with using two cups connected with a small or large length of string. Without realizing it, this little game created our very own private networks that we used for sharing secrets and gossip. Ad hoc networks are somewhat similar. They form temporary networks between two or more wireless devices anywhere without the need for a fixed infrastructure to control the way data packets are routed.
Why are these important? For one, this can be used in very remote terrain for easy communication or to create safer wireless networks for small durations to exchange data quickly without being intercepted.
One of the categories of ad hoc networks is known as Vehicular Ad hoc Networks or simply, VANETs. Today, let us take a look at this little-known technology that is behind connected and autonomous vehicles!
