Summary:PURPOSE: An energy cognitive routing method considering mobility in a sensor network and a device thereof are provided to set a route in consideration of a remaining energy amount of a sensor node, thereby lengthening lifetime of a wireless sensor network. CONSTITUTION: A mobile node transmits a help message to adjacent nodes in consideration of an available remaining energy amount(S120). The mobile node checks a response for the help message(S122). When the mobile node does not receive a route setup message from the adjacent nodes, the mobile node notifies data transmission unavailability to a previous sensor node(S130). When a sensor node requesting data transmission to the mobile node is not a source node, the sensor node deletes route information for information for the mobile node(S132,S134).
