Abstract: A method for supporting energy efficient mobility in a sensor network is provided to uniformly use energy of all sensor nodes in consideration of a power amount of each sensor node in a seamless data transmission process, thereby lengthening lifetime of the entire network. A mobile node determines whether handoff is necessary through strength of an RF(Radio Frequency) signal and power amount received from at least one neighbor sensor node(S200). If the handoff is necessary, the mobile node determines a switching sensor node through the strength of the RF signal and power amount(S205). The mobile node performs handoff into the switching sensor node based on information of the selected switching sensor node(S210).
