Abstract
Generally, this disclosure describes a method and system for peer-based collaborative discovery and signaling of another device in limited signal areas. A method may include, in an embodiment, initiating a sensing mode in a seek mobile device in response to receiving an indication that a location of a lost mobile device is unknown; capturing first position data if a signal from the lost device is detected; capturing second position data in response to losing the signal from the lost device; and determining an estimated location of the lost device based on the first position data and the second position data, wherein the lost device is located in an area of limited or no connectivity and the seek device is moving through the area.
