  • For scanning, datagram sockets are the way to go.

    You bind a datagram socket to the same multicast port on both PC and mobile, and every one in a while you broadcast a message to the port. Because it is a multicast message, every device on the network will get the message.

    When you get a message on a multicast port, the datagram socket's MessageRecieved event handler will trigger. This will allow your reciever to send a message back to the sender and thus respond to the multicast.

    this is called SSDP. You can learn more from this link.
