Portable battery operated electronic devices often use a “sleep mode” for energy
conservation. A key feature introduced in the IEEE 802 standard ensures power-efficient
operation of these battery operated mobile devices. However, the standard fails to define
what will trigger a device into the sleep mode while other systems define “waiting time
threshold” as a time for which a Mobile Subscriber Station (MSS) waits before entering into
sleep mode which has a constant duration. An embodiment of the present invention uses a …
