Abstract
Embodiments of the present invention provide a method of reducing power consumption in a wireless network device, comprising determining a duration prior to a beacon being received by the device; comparing the duration against a predetermined value; and adjusting a duration of a sleep period in response to the comparison.
Claims20
A method of reducing power consumption in a wireless network device, comprising:
- receiving a beacon periodically broadcast at a beacon broadcast interval in a wireless network;
- determining, by a processor, a sleep duration based at least in part on the beacon broadcast interval;
- and
- adjusting the sleep duration, in response to receiving an external interrupt, by subtracting a time for which the wireless network device has slept during a most recent sleep period from the beacon broadcast interval.
A wireless network device, comprising:
- a receiver configured to receive a beacon periodically broadcast at a beacon broadcast interval in a wireless network;
- and
- a processor configured to:
- determine a sleep duration of the wireless network device based at least in part on the beacon broadcast interval in the wireless network, and
- adjust the sleep duration, in response to receiving an external interrupt, by subtracting a time for which the wireless communication apparatus has slept during a most recent sleep period from the beacon broadcast interval.
A non-transitory computer readable medium having instructions embodied thereon for reducing power consumption in a wireless network device, wherein the instructions, in response to execution by the wireless network device, cause the wireless network device to at least:
- receive a beacon periodically broadcast at a beacon broadcast interval in a wireless network;
- determine a sleep duration based at least in part on the beacon broadcast interval;
- and
- adjust the sleep duration, in response to receiving an external interrupt, by subtracting a time for which the wireless network device has slept during a most recent sleep period from the beacon broadcast interval.
