In WPAN environment using the existing ZigBee communication, the determination of transmitting electric power output of sensor is set up at the early stage which composes system. Therefore, the devices which compose WPAN use the way to transmit with the output value that is set as fixed irrelevantly to the distance of other device and it causes excessive electric power for transmitting. As a result, the life-expectancy of battery is reduced and there happens interference among devices. So, in this paper, a transmit-receiving system which can transmit signal using proper electric power for transmit to other device that transmits signal by the receiving intensity of measured signal after measuring intensity of RSSI of each device for solving interruption problem among device and wasting electric power transmitting.
