Abstract
A method and system of time-offset based synchronization for mobile device indoor navigation and positioning. The method, executed in a processor of a server computing device, comprises receiving, at a set of fixed nodes, a wireless signal transmission from a moving node; deriving a time difference of flight (TDOF) offset amongst the set of fixed nodes and the moving node; and localizing the moving node at a given time based at least in part on the TDOF offset.
