Abstract
A method of performing handover using subnet information includes: comparing subnet information for the current PoA with subnet information for the new PoA; and determining a layer in which handover is performed, according to whether the subnet information for the current PoA is equal to the subnet information for the new PoA, and performing handover in the determined layer. By comparing subnet information received before a mobile node moves with subnet information received after the mobile node moves, and thus quickly determining whether a change between subnets occurs, and by determining a layer in which handover is performed on the basis of the determination result, it is possible to efficiently perform handover.
