Energy saving system and its method in distribution type radio individual area network

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.

Description

[0001] This application claims the benefit of Indian Patent Application No. 553 / CHE / 2004 filed on June 14, 2004 and Korean Patent Application No. 2004-111380 filed on December 23, 2004, the entire contents of which are incorporated herein by reference for reference. technical field [0002] The present invention relates to an energy-saving system and method in a distributed wireless personal area network, and in particular to an energy-saving system in a wireless personal area network based on a mobile specific (ad-hoc) network in a distributed wireless personal area network Energy-saving system and method for media access control. Background technique [0003] A WPAN (Wireless Personal Area Network) is defined as a network operating within a private domain of approximately 10 meters. IEEE (Institute of Electrical and Electronics Engineers) is involved in determining standards for such wireless personal area networks. UWB (Ultra Wide Band) communication technology can prov...

Problems solved by technology

[0021] However, as discussed in the MBOA MAC v0.5 specification, existing methods have the problem that if any device does not acknowledge that a particular device has passed the beacon through which it declares its intent to enter sleep mode, then the device It is not known when the sleeping device will return to active mode

Therefore, the device can remain active continuously for a long time in order to communicate with such a device, and this long waiting time will cause a drastic reduction in the power storage of the corresponding device
