the theory of building mesh networks and development skills for android. it's obvious, isn't it?

Answer 3

What features can be in the development of such an application, and will it differ greatly from the development of a regular messenger?

Actually, the peculiarity lies precisely in the fact that you have to write a layer responsible for organizing routing in a mesh network. After you write this, that is, your product will allow you to identify, route and connect any pair of nodes in the network, further development of the messenger will be almost no different from the development of a "regular" messenger. But you need to understand that the first stage (implementation of a mesh network) takes, offhand, no less than a man-year and requires a good study of the mathematical model of the network.
