Abstract
A method for Internet Protocol (IP)-based sleep mode control is disclosed. The method includes, when a request for a sleep mode is made from any one of internal hosts, transmitting a sleep mode request message to an internal router, updating the state of the corresponding host to a sleep mode, transmitting a sleep mode ACK message to the internal host requiring a sleep mode, switching to a sleep mode, and transmitting information about the internal hosts in a sleep mode to the external hosts of a history information list because the internal router stores the history information of the external hosts that communicated with the internal hosts in a sleep mode in the form of a list.
