    摘要: Provided is a probing method for handoff including constructing a group of neighbor access points of a current access point with which the station associated, generating subgroups of the neighbor access points by the channel assigned to the access points, probing the access points by subgroup in a subgroup selection order, and selecting the neighbor access point having best link quality as a target access point to handoff. The probing method of the present invention is implemented with a novel non-overlap graph for constructing the neighbor graph such that the probing latency is dramatically reduced, resulting in reduction of handoff delay.

    摘要: A computer-implemented method for scheduling a packet for transmission in a wireless local area network can be used to account for hidden and/or exposed terminals. The method includes determining whether the packet is to be transmitted to a computing device through a wireless access point that is in conflict with at least one other computing device associated with a different access point. The method further includes determining whether there is a conflicting packet scheduled to be transmitted for any conflicting computing devices associated with a different access points and scheduling the packet for transmission based on any conflicting packets. The method yet further includes forwarding the packet to a wireless access point at the scheduled time.

    摘要: The invention pertains to location approximation of devices, e.g., wireless access points and client devices in a wireless network. Location estimates may be obtained by observation/analysis of packets transmitted or received by the access point. For instance, data rate information associated with a packet is used to approximate the distance between a client device and the access point. This may be coupled with known positioning information to arrive at an approximate location for the access point. Confidence information and metrics about whether a device is an access point and the location of that device may also be determined. Accuracy of the location determination may be affected by factors including propagation and environmental factors, transmit power, antenna gain and diversity, etc. A location information database of access points may employ measurements from various devices over time. Such information may identify the location of client devices and provide location-based services to them.

    摘要: Improved battery life for mobile wireless devices communicating using standard network protocols is obtained by measuring an energy profile of the transmitter circuitry with respect to transmission rate and transmission energy and adjusting operating conditions according to measured or deduced error rates. Additional energy savings are obtained reducing the total number of bits transmitted using payload compression and header truncation making use of application layer communications between the remote device and a power-unconstrained proxy device.

    摘要: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for geographic annotation of electronic resources. In one aspect, a method includes generating a spatial index for a plurality of resources from a plurality of distinct publishers, including, for each resource of the plurality of resources: receiving a plurality of location data points for the resource, each location data point corresponding to one of a plurality of requests for the resource, and assigning each location data point for the resource to a spatial cluster of a plurality of spatial clusters, each spatial cluster corresponding to a particular geographic region. The spatial index is stored. The spatial index is used to identify a plurality of address locations for resources assigned to a spatial cluster corresponding to a first geographic region in response to a request from a requester to identify resources associated with the first geographic region.

    摘要: Systems and methods are provided for real-time information sharing. A server receives, from a first user device, a request to create an event and to share information among a group of user devices only within a predetermined time period. The server receives information from the respective user devices in the group during the predetermined time period, and distributes the received information to the group of user devices during the predetermined time period. The information comprises at least one of geographic locations of the group of user devices and still pictures or video taken by one or more of the group of user devices during the event.
