Power management methods and systems
Power management methods and systems for a first station and a second station in an ad-hoc network. Each station enters the normal beacon interval (NBI) every certain number of beacon intervals (BIs) for data transmission, a Listen Interval (LI). When a station switches to a power-saving mode, it fi...

| description | Power management methods and systems for a first station and a second station in an ad-hoc network. Each station enters the normal beacon interval (NBI) every certain number of beacon intervals (BIs) for data transmission, a Listen Interval (LI). When a station switches to a power-saving mode, it first determines the number of "beacon-window-only beacon intervals (BBIs)" within a LI. In addition, each station broadcasts a beacon frame comprising at least information about "the remaining number of BIs (RBI)" within a beacon window. Once the first station correctly receives the beacon frame from the second station, the first station predicts the NBI of the second station according to the RBI. At the NBI of the second station, the first station transmits data frames to the second station. |
