Hi Jeongki ...

I am not so sure, but IIRC sending to broadcast address such as 
192.168.255.255 on 192.168.0.0/16 network will do what you want. As for 
receiving the broadcast data, I think simply listen to the designated port 
will do the trick. Mind you again, this is just my guess.

Feel free to CMIIW people...

regards,

Mulyadi
