  • Patent number: 8848513
    Abstract: A communication system enables a node to utilize multiple communication interfaces to connect to an overlay network. The use of multiple communication interfaces provides a redundant overlay network connection, thereby enabling a node to maintain connectivity or select a preferred connection to the overlay network, increasing efficiency or reducing costs in the overlay network. A network in which member nodes obtain services in the absence of server-based infrastructure is referred to as a “peer-to-peer overlay network” (or “overlay network” or simply “overlay”). Overlay networks consist of several nodes from hundreds, to thousands, joined together in a logical routing structure. Individual nodes often participate in routing and maintenance aspects of the overlay. Typically an overlay is formed through the enrollment and joining of all these nodes as defined by the overlay protocol. Nodes forming peer-to-peer overlay networks may communicate with each other over various network technologies.

  • Publication number: 20140257688
    Abstract: Systems, apparatus and methods disclosed herein facilitate mobile station (MS) location determination using MS captured images of known points of interest (POIs). In some embodiments, each POI is associated with a corresponding visibility map comprising a set of grid points, and a subset of the POIs may be identified from the MS captured images by matching the MS captured images of each POI in the subset with corresponding stored images. A cumulative grid point weight for a plurality of grid points in the visibility maps associated with the POIs in the subset may be computed. The cumulative grid point weight for each grid point represents the probability that the MS is located at that grid point. The location of the MS may be estimated based on the cumulative grid point weights of the plurality of grid points.
