    摘要： Systems and methods are described for using client conduits to enable bootstrapping and fault diagnosis of disconnected wireless clients. Client conduits are used to enable disconnected clients to diagnose their problems with the help of nearby clients. This technique may take advantage of the beaconing and probing mechanisms of IEEE 802.11 to ensure that connected clients do not pay unnecessary overheads for detecting disconnected clients. Methods are also described for detecting rogue devices disguising as disconnected clients.

    摘要： Methods of reducing power consumption in a computing device are described in which file sharing applications which are running in the background are offloaded onto a lower power subsystem and the rest of the computing device can be put into a low power state. The lower power subsystem runs application stubs which autonomously execute a subset of the operations performed by a file sharing application which was previously running on the computing device. Before the rest of the computing device goes into the low power state, application state information is passed to the lower power subsystem for use by the application stubs. In an example, the application stub may continue to download files whilst the rest of the computing device is in standby or is shutdown and the application state information may include details of the files that are to be downloaded.

    摘要： Candidates that are potentially responsible for user-perceptible network problems may be inferred. In an example embodiment, a system includes an inference engine to produce a list of candidates that are potentially responsible for user-perceptible network problems, with the candidates being network components that may include both services and network elements. A response to a service request may be a non response, an incorrect response, an untimely correct response, or a timely correct response. The user-perceptible network problems may include the untimely correct response as well as the non response and the incorrect response. In another example embodiment, a method includes monitoring a network and producing a list of candidates that are potentially responsible for user-perceptible network problems. The candidates of the list may include both services and network elements of the monitored network.

    摘要： Methods are described for using collaboration of neighboring wireless devices to enable location of disconnected wireless devices and rogue wireless access points. A central server computes the locations of the neighboring clients and uses those locations to estimate the location of a disconnected client. These techniques may take advantage of the beaconing and probing mechanisms of IEEE 802.11 to ensure that connected clients do not pay unnecessary overheads for detecting disconnected clients. Methods are also described for detecting and locating rogue devices by collaboratively collecting information from neighboring devices and comparing the information to a database.

    摘要： A system and method that increases the capacity of a wireless network using frequency diversity. A user switches between channels of a network using a single network interface card in such a manner that nodes desiring to communicate overlap while disjoint communications mostly do not overlap. A driver is inserted into a device's networking stack and controls the network interface card using a plurality of virtual wireless network adapters. Packets for a recipient are queued when the recipient is not accessible on the node's channel. In one embodiment where multiple nodes are switching in and out of channel, the method changes part of a nodes channel hopping schedule to ensure concurrent connectivity in a channel for at least a brief time period such that packets can be received/transmitted with desired nodes.
