摘要： 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 of 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.

摘要： Packet communication method and system in which a packet destined for a terminal is provided service according to a service table indexed by packet classification and the terminal's power mode. The service table may specify for a connection a predetermined quality of service or discarding the packet. For a power mode having an alerting (i.e., paging) mechanism, the service may include alerting the terminal. The service table may also include a network edge point's own service requests and service requests from terminals, provisioning servers, and handoff sources. For a multicast or broadcast packet, as each terminal may be in a different power mode, the associated service in the service table may therefore be different for each terminal. In that case, the packet is provided with service so that any given terminal is provided with at least the quality of service specified in the service table. Thus, a multicast or broadcast packet is discarded when the service specified for all terminals is “discard.” Each terminal is alerted, however, if the associated service includes alerting the terminal. During handoff, a part of service table associated with the terminal can be transferred from the handoff source to the handoff destination.

摘要： A method for power saving in an ad hoc wireless computer network determines an optimal ATIM message exchange window. The method (a) determines an effective number of nodes that participate in exchanges of ATIM messages during an ATIM window; (b) using the effective number of nodes, calculating a length for a data frame transmission window; and (c) calculates a length for the ATIM window using the calculated data frame transmission window. In one instance, the method determines the effective number of nodes based on the number of senders of ATIM messages. In another instance, the effective number of nodes is determined based on both senders and recipients of the ATIM messages. The method may determine the effective number of nodes from a number of successful ATIM message transmissions in a given time period. The calculated ATIM window size can be provided as an initial value to other methods that dynamically adjust the ATIM window size.

摘要： Methods are disclosed to support power saving states of a beacon station in an ad hoc wireless local area network (WLAN). Some of the methods allow exchanging power management information among stations in the wireless network and to allow beacon station handovers. In some methods, always-on stations are given a higher priority to become a beacon station or a beacon station handover destination. The methods achieve good power saving while minimizing beacon handover frequency.

摘要： Channel scanning for wireless networks, such as Wireless Local Area Networks (WLANs), generally provides a wireless station with the information on the available WLAN resources, such as the frequency band and the maximum transmission power. The present invention provides safe and fast domain-aware channel scanning, enabling a wireless station to comply with applicable local regulations, in spite of the possibility of domain changes, with short channel-scanning time. Fast channel scanning is accomplished by active channel scanning if valid domain information is available and there is no possibility of domain change. Also, domain-independent channels, if any, are first scanned using active scan to get domain information faster.
