Yes, i modified the code. the default value of REPOAWER is 31 at the maximum in Tinyos1.15. Then I changed it to 1. I believe nothing changed. The node still can communicate with other nodes at least 15 meters. It is not that good. I will try to use setRFPower. Is this the right value I should change in order to decrease the transimission distance. I am confused. Anyone who has experience, please help me. THanks in advanced.
