Have you heard about LAN Messenger?

LAN Messenger is a free and open source cross-platform instant messaging application for communication over a local network.
It does not require a server.
A number of useful features including event notifications, file transfer and message logging are provided

If we want to communicate with anyone we have to have a server between the towo to communicate with each other easily
But if we want to communicate with the local network near by or in the home network we can use the LAN Messenger to chat between each other
We can even share images between the two

One of the worst things in a household full of people is, when everyone starts having conversations throughout the house.
Parents shout to the kids upstairs, kids shout to each other from one bedroom to the next, and it's enough to give a person a pounding headache after a long and busy day at work.
Of course, with the advent of so many electronics throughout the home – laptops, tablets, smartphones, game consoles and other devices that are able to plug into the home's wireless LAN – more families are turning to instant messaging as a solution for in-home communication.
Heck – IM is making paging systems obsolete at most workplaces, so why not in the home?

The problem arises for parents of young children, who don't want those kids to be plugged into the Internet on public IM networks – for those parents, LAN Messenger can serve as an excellent solution.
