摘要： A method and apparatus for managing simultaneous virtual connections with multiple wireless networks. A plurality of ports in a hardware driver may be each associated with a corresponding wireless network and maintain a unique MAC state relative to other ports. Each port may have a corresponding virtual NIC that communicates directly with the radio hardware via a hardware virtualization layer that multiplexes communication between the virtual NICs and the radio hardware. Simultaneous virtual connections may be made with one or more infrastructure networks or adhoc networks, and/or the computer may function as an access point for one or more of the networks.

摘要： A method and system for scanning in a wireless device having a wireless network interface card (NIC) is presented. The system has a scanning history table for storing scanning results and a scanning engine that adjusts the scanning period based upon a history of scanning results and commands the NIC to scan for available networks after the period has expired. The engine receives scan results from the NIC, stores the scan results in the scanning history table, determines a scanning period based upon a history of scan results, sets the scanning period, and commands the NIC to scan for available networks after the scanning period has expired. The engine is programmed to set the scanning period using an exponential function and to reset the scanning period to a default period if the scan results are different from a prior scan result or if a triggering event is received.
摘要翻译：提出了一种用于在具有无线网络接口卡（NIC）的无线设备中进行扫描的方法和系统。系统具有用于存储扫描结果的扫描历史表和基于扫描结果的历史来调整扫描周期的扫描引擎，并命令NIC在该时间段到期之后扫描可用网络。引擎从NIC接收扫描结果，将扫描结果存储在扫描历史表中，根据扫描结果的历史确定扫描周期，设置扫描周期，并命令NIC扫描可用网络，扫描周期为已过期引擎被编程为使用指数函数设置扫描周期，并且如果扫描结果与先前的扫描结果不同或者如果接收到触发事件，则将扫描周期重置为默认周期。

摘要： A software based wireless infrastructure system is provided. The system has a driver that communicates with the network stack and a network interface card (NIC), a station server in communication with the station driver and an 802.1X supplicant or an 802.1X authenticator. Each NIC provides station and/or access point functionality support. The driver drops packets that have been received if the packet has not been authenticated and associated. Packets that have been fragmented or encrypted are unfragmented and decrypted. An association manager is used in conjunction with a configuration table manager to associate stations and access points via management packets. A manager receives 802.1X data packets from the packet processor and sends them up to a station server that communicates with user mode applications and an 802.1X supplicant or an 802.1X authenticator that are used to authenticate and deauthenticate stations and access points. APIs are provided to enable communication between the components.

摘要： An architecture and methods for extending the depth of a WLAN to a four-level hierarchal access point structure including wireless access points. The wireless access points in the WLAN can be networked by scanning for a network, collecting one or more packets that identify the network from one or more access points, each packet including an address identifying an ancestry of the access points to an ancestral wired access point; and applying an access point selection algorithm to configure a parent access point. The architecture includes a scanning object configured to issue a scan request to a network interface and collect access point data; a selection object configured to filter and sort the collected access point data; an authentication state machine configured to perform authentication and validate; and an association state machine configured to compose a packet including hierarchical data indicative of access point ancestry to a conventional access point.

摘要： Described is a protocol by which wireless network communication devices comprising peer nodes (such as a computer system and an access point) cooperatively exchange information about RF interference detected in the network. The protocol administers the exchange of formatted control data corresponding to the detected interference among computing nodes running a service capable of processing the control data. A peer table is used to maintain locally-obtained and remotely-obtained control data. Records in the peer table are arranged with different levels of granularity with respect to interference and networking information. The interference information collected through the cooperative protocol may then be used by peer devices in the network to adapt to mitigate interference-related problems. The protocol also provides for discovery of peer node capabilities, including a negotiable transport for the control data that may be different from the main data channel transport.

摘要： The principles of the present invention provide for providing contention free quality of service to wireless stations. A station indicates to an access point that higher priority data (e.g., time constrained data) is to be sent to the access point. The access point receives the indication and selects a slot time for the station based on the number of other stations that have also indicated higher priority data. A slot time is selected such that the station can check for access to a common wireless link before any stations with lower priority data (e.g., data without time constraints). The access point sends the selected slot time to the station and the station receives the slot time. When the station receives an indication that an application has higher priority data to send, the station checks the common wireless link for availability at the selected slot time.

摘要： A wireless mesh network enables multiple devices near each other to transmit simultaneously, thus allowing increased network bandwidth. Prior to transmitting, a device may determine various parameters of the wireless medium on which it desires to transmit. For example, the device may determine whether the intended recipient device is close enough, and verify that any other transmitting and receiving devices are far enough away. If these or any other suitable criteria are met, the device can transmit simultaneously with other devices in the vicinity.

摘要： A method and system for managing power consumption in a portable computing device having a network interface module is presented. A power management module receives inputs from other modules and determines when the network interface module is to be put in a doze state for a predetermined number of beacon intervals to conserve power consumption in the network interface module. The network interface module in a device that is associated with a network is put in the doze state after an event has occurred including when a scan has been performed, after a delayed sleep timer has expired, and after a beacon transmission has been completed and no traffic is buffered for the device. The delayed sleep time is set based on the estimated round trip time of a packet.

摘要： A network node selects a “sleep” level based on its current or projected battery capacity. In an embodiment of the invention, sleep levels define the types of communication to which the node in question will be a party. The node in question communicates its selected sleep level to the rest of the network so that the other network nodes can communicate accordingly with the node.
