Abstract: An RSSI(Received Signal Strength Indicator) measuring method for the configuration of a wireless sensor network and a PRMD(Portable RSSI Measuring Device) are provided to grasp the communication environment exactly at a place expected to install a new communication node by detecting communication quality in actual communication with communication nodes of a wireless sensor network system at the expected place. A PRMD comprises a communication module(14), a display unit(16), a control part(10). The communication module performs communication with communication nodes of a wireless sensor network system. The control part transmits a communication quality detection request message to one or more of the communication nodes of the wireless sensor network system at a place expected to install a new communication node. If a response message containing transmission quality information is received from a communication node, the control part detects reception quality information for the received response message. Also the control part displays the detected reception quality information and the transmission quality information, contained in the received response message, through the display unit.

Abstract: A method for scanning a transmission energy level according to the distance between nodes and a recording medium storing the same are provided to perform routing with the least transmission energy of a network by performing communication through only an amount of energy suitable for the distance between nodes. A coordinator starts the first stage of scanning(310). The coordinator checks whether there is a response to the scanning(320). When an association request is received within a scan response standby time in response to the scanning, the coordinator gives an ID to a node which has responded by using the same energy level, adds information on the node to an energy level table, and performs responding to the association request(330). The coordinator requests a router that appears first in its energy level table to perform the second stage of scanning in the similar manner as that of the coordinator(340).
