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 ad hoc network identifier may be received, for example, at an ad hoc network convergence module. One or more ad hoc network parameters may be generated as a function of the ad hoc network identifier. Each of a group of computers attempting to form an ad hoc network identified by the ad hoc network identifier may generate the one or more ad hoc network parameters. Two or more of the group of computers may perform an ad hoc network formation protocol parameterized with the generated one or more ad hoc network parameters. An instruction to join the network may be received, for example, at a networking service. If it is detected that the network is an ad hoc network, an ad hoc network address acquisition mode featuring accelerated ad hoc network address acquisition may be activated. Efficient formation of the ad hoc network may thus be facilitated.

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： A process for secure, safe, and easy provisioning of a wireless device with credentials to connect to a wireless network. A connecting wireless device and an established wireless device both utilize low power transmission at close proximity to exchange wireless connection setting information and/or a password. The connecting wireless device is moved into proximity with the established wireless device and a low power setting is discovered at which the wireless devices may communicate with a sufficiently low error rate. The connecting wireless device is then passed the secret information by the established network device.

摘要： A wireless device that desires to be connected to a wireless network broadcasts itself and its capabilities to a network using an information element. The information element is provided with frames, such as management frames, in a channel that is not protected or encrypted. The information element is forwarded to one or more potential registrar devices. One of the registrar devices then provides configuration information to the enrollee, for example as a registrar information element. The configuration information may be passed out of band or in band, and may be passed using cryptography, which may involve public key cryptography, encryption with a PIN, or some other type of secure exchange.

摘要： A wireless device communications mode selector dynamically establishes an optimal communication mode between wireless devices and/or access point, such that stations communicate directly with each other or indirectly through an existing AP depending upon which mode would yield higher throughput under present network conditions and configuration. In an embodiment of the invention, a measurement based mechanism is used to decide which communication mode is more efficient. If it is decided that direct communication is optimal, the two stations can either form an adhoc network or an STA can be dynamically configured to become a wireless repeater access point (soft AP).

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 system and method for carrying out network and interface selections across multiple media is disclosed. The disclosed system facilitates automated network interface configuration decision-making that spans a set of networks supporting communications via differing media. A set of media specific modules associated with differing communications media acquire network interface status/capabilities information. A rules engine thereafter applies a designated network selection rule(s) to the acquired network interface status/capabilities information, and any other appropriate parameters attributable to either an interface or network, to select one or more networks and interfaces with which to establish/maintain a connection.

摘要： To reduce the power consumption of a wireless communication hardware device, power conservation scheduling algorithms can be implemented. Reoccurring events, including DTIM intervals and listen intervals can be scheduled as awake times. Similarly expected response intervals can be scheduled as awake times based on information, such as round trip time, that can be passed together with data to be transmitted. The wireless communication hardware device can be placed into a doze state unless it is transmitting data, or unless it is expecting a transmission during one of the scheduled awake times.
