    摘要: A system and method is provided that allows a client device to determine its position based on the location of signals detected by the device. The signals' locations may be obtained from a server, and some of the information may be pre-fetched and sent to the client device before the client device detect the signals. The pre-fetched data may also be encrypted so that a client device cannot determine the location of a signal unless it is proximate to the signal.

    摘要: In general, aspects of the present disclosure are directed to techniques for detecting proximity between computing devices. A first computing device may query a server device. Subsequent to querying, the first computing device may receive instructions from the server device to re-query the server device at a first specified time. The first computing device may re-query the server device at the first specified time. Subsequent to re-querying, the first computing device may receive an address associated with a second computing device and instructions from the server device to connect to the second computing device at a second specified time. The first computing device may connect with the second computing device at the second specified time based at least in part on the address associated with the second computing device.

    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: 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: A roaming service method for a fast and secure wireless network is provided. In an embodiment of the present invention, an AP, which an STA associates with, transmits proactive keys needed for roaming to neighbor APs of the AP. When the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided proactive key. In another embodiment of the present invention, an authentication server transmits proactive keys needed for roaming to neighbor APs to which the STA is likely to move, so that when the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided proactive key.
