Enhanced IEEE power save in ad hoc wireless mode

摘要

In accordance with the invention, a method, system and apparatus for saving power consumed by a station in an ad hoc wireless network are presented. The method comprises transmitting or receiving a signal by a station in the ad hoc wireless network during a beacon interval. The station enters a power saving doze state immediately following the transmission or reception of the signal and prior to the end of the beacon interval. Additionally or alternatively, the station may enter power saving doze state following a timed period, according to a counter, or according to a periodic pattern.

1. A method for saving power by a device in communication with an ad hoc wireless network, the method comprising:
during a beginning portion of each of multiple beacon intervals, transmitting, by the device, a respective beacon; and for each respective beacon interval of the multiple beacon intervals,
determining whether an announcement traffic identification message (ATIM) is one of (i) transmitted or (ii) received by the device after the transmission of the respective beacon and during the respective beacon interval,comparing a counter to a threshold,(A) if the counter is less than the threshold and (B) if no ATIM is one of (i) received or (ii) transmitted during the respective beacon interval, incrementing the counter, andif the counter is equal to the threshold, having the device enter a power saving doze state during at least a part of the respective beacon interval.
