摘要： A system for saving energy through control of a sleep mode, and a method of operating the system are provided. The energy-saving system may enable a proxy device to maintain a minimum basic setup necessary for a communication when a host device enters a sleep mode, and may omit an operation performed based on the basic setup when the host device switches to a communication mode, thereby enabling a smooth switch between the sleep mode and the communication mode.

摘要： In transferring a service context during hand-over of a mobile node located in a wireless mesh network, transfer boundaries are set according to positions spaced from an initial Access Point (AP) to which the mobile node is initially connected to, AP types being determined based upon the set transfer boundaries. Prior to hand-over of the mobile node in response to its movement, a service context is transferred to APs arranged in a moving direction of the mobile node based upon context transfer policies according to the determined AP types.
