Abstract: Methods and apparatus for merging peer-to-peer overlay networks. A method includes receiving an advertisement from a second overlay network, determining a size of the second overlay network, performing a self search on the second overlay network based on a persistent node identifier, if the size of the second overlay network is greater than the size of a first overlay network, and joining the second overlay network if the persistent node identifier is not part of the second overlay network. An apparatus includes a transceiver to receive an advertisement from a second overlay network, and a processor coupled to the transceiver to determine a size of the second overlay network, perform a self search on the second overlay network based on a persistent node identifier, and join the second overlay network if the persistent node identifier is not part of the second overlay network.

Abstract: The subject matter disclosed herein relates to systems, methods, apparatuses, articles, and means for determining at least one navigational coordinate system to be utilized in conjunction with transports and/or mobile devices. For certain example implementations, a method by a mobile device that is at least proximate to a transport may comprise identifying a first navigational coordinate system, with the first navigational coordinate system being associated with the transport and enabling navigation within at least one navigable area of the transport. A second navigational coordinate system may also be identified. The mobile device may determine to utilize at least one of the first navigational coordinate system or the second navigational coordinate system based, at least in part, on one or more predetermined conditions. Other example implementations are described herein.

Abstract: An example method for updating a wireless signal model includes: measuring a distance from a mobile station to each wireless access point, of multiple wireless access points, based upon a wireless signal model; calculating a position of the mobile station based upon the measured distance; determining a computed distance to each wireless access point based upon the calculated position of the mobile station; updating the wireless signal model based upon the measured and computed distances to each wireless access point; and determining whether the wireless signal model has converged.

Abstract: The subject matter disclosed herein relates to systems, methods, apparatuses, devices, articles, and means for updating radio models. For certain example implementations, a method for one or more server devices may comprise receiving at one or more communication interfaces at least one measurement that corresponds to a position of a first mobile device within an indoor environment. At least one radio model that is stored in one or more memories may be updated based, at least in part, on the at least one measurement to produce at least one updated radio model. The at least one radio model and the at least one updated radio model may correspond to the indoor environment. The at least one updated radio model may be transmitted to enable a second mobile device to use the at least one updated radio model for positioning within the indoor environment. Other example implementations are described herein.
