摘要： A system and method is described for saving power in a wireless network, using a physical layer address filtering protocol based on a partial address subset of the complete destination MAC address. The system comprises a PHY layer filtering protocol for generating the partial address and writing the partial address into a PHY layer header portion (e.g., PLCP header) of a sending station, or reading the partial address from the PHY layer header portion upon transmission of each frame. A receiving station receives and decodes these PHY layer header portion bits, in accordance with the protocol, and compares whether the subset of bits match that of the stations' own partial address. If a station finds a match, the station then continues further decoding the frame at PHY layer and send the complete frame to the MAC layer for further processing. The stations that do not have a match will not activate their MAC layer components. Thus, the stations of the network will avoid wasting power decoding a significant portion of the complete frame of other stations of the wireless local area networks and unnecessary MAC layer processing. When group addressed, control/management frames or other such frames are detected at the sending station, the address filtering protocol may be “disabled” using a partial address containing a predetermined value (e.g., all zeros).

摘要： A new system and method is described, utilizing a scheduler based on a transmission power consumption calculation and prioritizing algorithm. The system utilizes the (APSD) protocol specified in the 802.11e draft for saving power in wireless local area networks. The system comprises an access point having a priority queue, one or more stations, an APSD frame comprising an association ID for identifying one of the stations and a scheduled wake-up time for the identified station. An algorithm is employed for calculating the total transmission power consumption of downlink data for the stations. The AP originates and transmits to the one or more stations the APSD frame of the scheduled activation delay time. The current data to be transmitted to each station is accessed by the algorithm to determine the total transmission power consumption to each station. A priority queue in the AP is ordered from the lowest to the highest receiving power consumption, assigning the highest priority to the lowest power consumption transmission to minimize total power consumption to the PS stations in the AP queue.

摘要： The various embodiments of the invention relate to analyzing operations of an emulated input-output processor. Instructions native to the first type of instruction processor are emulated on a second-type instruction processor. The instruction processor emulator executes an operating system that includes instructions native to the first type of instruction processor. The operating system includes instructions that write input/output (IO) requests to the memory arrangement in response to IO functions invoked by a program. An IOP emulator that is executable on the second-type processor emulates IOP processing of IO requests from the memory arrangement. The IOP emulator maintains in the memory arrangement a first set of data structures used in processing the IO requests. State data currently contained in the data structures is stored on a retentive storage device, and in response to user input controls, the state data is read from retentive storage and displayed.

摘要： A new protocol system and method is described that utilizes a Schedule Information Vector (SIV) protocol for saving power in wireless local area networks. The protocol includes an access point, one or more stations, and an SIV frame including an association ID for identifying one of the stations and a scheduled wake-up time for the identified station. The access point originates and transmits the SIV frame protocol of the scheduled wake-up time to the stations. The SIV frame protocol of the wireless network is further operable to dynamically adjust the scheduled wake-up times of the stations, a sequence of the wake-up times, a periodic wake-up time, a plurality of wake-up times, and a duration of the wake-up times of the stations. These adjustments may be made based on network traffic, traffic buffering times, data priorities, data length, and data rates.

摘要： A wireless network, including a plurality of network elements such as a wireless access point (9), and computer stations (2, 4, 6), is disclosed. The wireless network operates so that each network element (2, 4, 6, 9) waits for a pseudo-randomly selected duration, after the end of a frame on the channel, before initiating transmission. One of the network elements, such as the wireless access point (9), measures the performance of the network over a measurement period (T), and adjusts a minimum value of the upper limit of the range from which the random duration is selected, according to the performance of the network over the measurement period. The times measured may be the successful transmission time (Ts), which is maximized in adjusting the minimum value, or the idle and collision times (T1, Tc), which are equated in the optimization of the minimum value.
