What you are doing is multicasting which requires a UDP connection and special IP address ranges. I suggest you start with a Google search for UDP multicast and see what turns up.

It's simple. You just send packet to broadcast address.
i.e.
Your network: 192.168.1.0/24, then
broadcast address will be 192.168.1.255

And set the SO_BROADCAST socket option.
