The trick is making sure your motes are within the radio range of each other. You might have to move the motes closer to each other. This might work: Lets say you want three motes to form a multihop topology. Program one mote as root and two motes as non-root. Put the root at position A. Move one non-root mote farther from position A until you start seeing a drop in delivery ratio for packets from that mote. Mark that position as B. Then start moving the last non-root mote away from position B until you start seeing a drop in delivery ratio (position C). As you move the mote, first it might send the packet to the root directly, then it will send the packets via the non-root mote at B. This procedure might give you a rough idea on where you should put the motes (A,B,C) to form multihop topology. - om_p _______________________________________________ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
