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： A mobile network solution provides secure and portable wireless networking service to mobile users with devices equipped with wireless network interfaces. The Secure Nomadic Wireless Network, or SNOWNET, follows a hierarchical approach. Special SNOWNET nodes are deployed in the area where networking service is needed and form a backbone network. At the same time, SNOWNET nodes provide local access service to regular mobile clients. SNOWNET provides security through authentication of the nodes and clients, as well as through encryption of the data.

摘要： An improved system and method for wireless communications, as well as a method for configuring wireless communication devices for use in such a system, are disclosed. In at least some embodiments, the system for wireless communications includes a first wireless communication device configured for communication within a first frequency range, and a second wireless communication device configured for communication within a second frequency range, where the first and second frequency ranges substantially but not entirely overlap one another. Also, in at least some embodiments, the present invention relates to a method that wireless communicating devices can use in order to co-exist or utilize wireless channels that need not be non-overlapping. By allowing wireless devices to do this, it is possible to achieve greater usage of the wireless spectrum and as a result superior performance of the wireless communication system as a whole.

摘要： A method and system for assigning channels to a plurality of access points (APs) of a wireless communication network is disclosed. The method includes obtaining first information regarding first interference experienced by a first client due to multiple APs being positioned in proximity of that client, and obtaining second information regarding second interference experienced by either the first client or a first of the APs with respect to which the first client is associated, where the second interference is due either to others of the APs that are in proximity to the first AP, or to others of the clients that are in proximity to either the first client or the first AP. Additionally, the method further includes determining channel assignments for the plurality of APs based upon each of the first and second information.

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.

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.
