    摘要: An enhanced mobile communication device communicates directly with other enhanced mobile communication devices in an ad-hoc mode over a wireless medium. The device transmits and receives packets of digital data. The packets of digital data are such that when transmitted, the probability that they will be received by the other mobile communication devices is increased. The probability is further increased by transmitting the packets a multiple and variable number of times according activity in the wireless medium. Attempts to transmit are made periodically and the period of transmission is adjusted according to activity in the wireless medium. In a transportation application, the packets comprise vehicle traffic congestion update information. The device maintains a traffic database and a map database. Traffic congestion update information is exchanged with other devices. Routes through the map from a source or current position of the device to a destination are computed according to an analysis of the traffic database.

    摘要: A system and method splices into, or replaces routes identified based on road geometry with routes taken by the same user or other users to create alternate routes that may be selected by a user to display, for example, on a map or for which driving directions can be displayed. Communication of routes traveled by different devices may be received from a server or from another device. A naming convention for road segments and ordered paths of road segments is described.

    摘要: A system and method provides location-aware search results from a navigation or other device and provides one or more enhanced listings or advertisements with the results to offset the communication cost of the search. The sponsor may be charged for the listing or advertisement and the charge may be based on whether the device arrives in an area around the sponsor location within a threshold amount of time.
