Abstract
Enhanced power saving methods and systems for a powerline network improve power conservation by adaptively regulating the monitoring of a shared carrier sense multiple access (CSMA) region of a beacon period based on current need. The methods and systems include one or more enhanced power saving modes (EPSM). In some embodiments, EPSM include one or both of an enhanced priority resolution (EPR) mode and an enhanced idle sensing (EIS) mode. In some embodiments, an EPSM is selected from a plurality of EPSM in response to an EPSM indicator detected in a beacon region of the beacon period.
Claims18
An enhanced power saving method for a powerline network, comprising the steps of:
- detecting an enhanced power saving mode (EPSM) indicator in a beacon region of a beacon period;
- and
- selecting an EPSM from among a plurality of EPSM based on the EPSM indicator, wherein the plurality of EPSM comprise an enhanced priority resolution (EPR) mode and an enhanced idle sensing (EIS) mode.
An enhanced power saving method for a powerline network, comprising the steps of:
- monitoring a plurality of PRS slots in a shared CSMA region of a beacon period;
- monitoring a PPS slot in the shared CSMA region in response to a failure to detect a PRS in any of the plurality of PRS slots;
- and
- conditioning monitoring in the shared CSMA region after the PPS slot on whether a PPS is detected in the PPS slot.
An enhanced power saving method for a powerline network, comprising the steps of:
- monitoring for a valid transmission a predetermined window starting with a PRS slot and ending after a maximum contention backoff length in a shared CSMA region of a beacon period;
- and
- conditioning monitoring in the shared CSMA region after the predetermined window on whether a valid transmission is detected.
