Okay kiddo, a mobile ad hoc network (MANET) is like when you and your friends play a game of tag or hide-and-seek.
You all run around and hide from each other without needing a home base or central location to meet up.
In a MANET, devices like smartphones or tablets do the same thing, they connect with each other and pass along information without needing a centralized structure like a Wi-Fi router or cell tower.
They just create their own network on the spot as they move around.
This can be helpful in situations like camping or hiking where there might not be cell phone service or Wi-Fi connections around.
But you have to make sure to stay close to each other to stay connected and keep passing along the information, like a chain of kids passing a message from one end of the line to the other.
