Hello, first, you can set the power level to 1 - in this case the radio coverage is just half a meter approximately.
Also, you can use unicast messages which are sent to motes with a particular IDs. For example, if you need to measure multi-hop com delay, you can: 1) put motes with different IDs very close to each other (e.g. in a line); 2) send a radio frame from the mote with ID=n tothe mote with ID=n+1, retransmit it to the mote with ID=n+2, and so on. Of course it is not a real multihop communication, but it should work similarly: each mote transmits its frame to the next one.
