METHOD AND APPARATUS FOR POWER SAVING IN BEACON GENERATION OF WIRELESS NETWORKS IN AD HOC MODE |
摘要 |
<p>Methods for increasing power saving in a station that sends or receives frames in an ad hoc wireless network (e.g. IBSS), while allowing the station to enter a power-saving mode quickly upon completion of scheduled tasks. At the same time, a method the present invention allows two stations in the ad hoc wireless network to infer each other's power management mode without requiring an ATIM/ACK exchange between the STAs within an ATIM window. Consequently, a station may enter a power-saving mode promptly without impairing the station's ability to receive packets. In one embodiment, a "more data" field is used between stations to exchange information. Stations with various computation abilities provide information under different time constraints. The stations may enter power-saving modes that send multicast/broadcast frames or use promiscuous mode within an ATIM window.</p> |
