Abstract
A power saving system in distributed wireless personal area network and a method thereof are disclosed. A PS (Power Save) anchor that provides information about hibernating devices to a beacon group through power save information elements in media access control for a wireless personal area network based on a wireless mobile ad-hoc network. Accordingly, all devices in the given wireless personal area network can schedule their active modes and hibernating modes according to hibernating intervals of destination devices with which the devices want to communicate. This can effectively reduce the necessity of the devices' waiting for the destination devices to awake from the hibernating mode as the devices maintain their idle state, and thus the power consumption of all the devices in the network can effectively be reduced.
