hello,

the easyest way is bluetooth..
have a look on this
**broken link removed**
you can adapt your project with an Arduino unit.

cost of this YM-MCU bluetooth interface is very low (16€) , and act as a transparent RS232 link.
Distance can be more than 5 meters ( but < 15M trough walls)
I was able to drive my PIC DDS ,with the AMARINO 2 android application..
so you can also do it to drive your relays..
