Location Selection for Transmitting Emergency Beacons

Abstract:

Embodiments are disclosed for selecting locations for transmitting emergency beacons. In an embodiment, a method comprises: determining a current location of a mobile device in a geographic area; configuring a transmitter of the mobile device for device-to-device (D2D) communication; determining one or more candidate transmit locations for D2D communication, wherein each candidate transmit location is determined based at least in part on its elevation, proximity to a D2D device density location that is within a maximum communication distance from the candidate transmit location, and an availability of a trail or path to the candidate transmit location; receiving input selecting a particular candidate transmit location from the one or more candidate transmit locations; in accordance with the input, determining a route from the current location of the mobile device to the particular candidate transmit location; and presenting the route through an output device.
