<p>PURPOSE: A routing device and a method thereof in a Zigbee network performing the routing at minimum cost in consideration of a battery power level are provided to calculate the routing cost in consideration of the battery energy of a Zigbee node. CONSTITUTION: A communication module transmits and receives signal for communicating with the other node. A controller(840) obtains the location information and a battery power level of one or more node through the communications module. The controller decides the routing route having the minimum routing route cost based on the location information. In case the status information or the location information is requested through the communications module, the controller decides the status information or the location information. The controller transmits the status information and location information.</p> |
