You must reduce the transmission power. With "SetRFPower" (C:\cygwin\opt\moteiv\tos\lib\CC2420Radio) command you can adjust the transmission power from your aplication. If you do not use this command, the default power transmision is set to 0x1F (31 -> 0 dBm -> max power) in "CC2420Const.h" file (in the same folder).

Subject: [Tinyos-help] Reduce tmote radio range

Hello everyone,

   I want to reduce the range of tmote so that i can get a multi hop topology. There are posts that say to change the CC2420Radio file parameters. Which parameters should i change in which file in that folder ??

Thanks,
