Abstract
Methods, systems, and computer program products for crowd-assisted micro-navigation are provided herein. A method includes determining a navigation route between a first user device and a second user device within a given environment; defining a virtual boundary to surround the navigation route; implementing a first set of one or more additional user devices within the given environment to (i) detect movement of the first user device outside of the virtual boundary and (ii) generate an alert upon detection of movement of the first user device outside of the virtual boundary; and implementing a second set of one or more additional user devices within the given environment to measure a wireless signal received from the first user device to enable triangulation of the location of the first user device, in response to the alert.
