Abstract

Devices, systems and methods are disclosed for creating a self-organized time-synchronization network, enabling accurate synchronization. For example, multiple devices may wirelessly broadcast and receive beacon signals and self-organize into an ad hoc network. The wireless ad hoc network may be optimized as individual devices choose new connections to reduce a number of hops to a source device. Individual devices may include a counter that may increment continuously for timing purposes, and counters may be synchronized between connected devices. For example, a local device may adjust contents of a local counter on the local device based on a drift between the local counter and a remote counter on a remote device. Thus, counters between connected devices may be synchronized, beginning at the source device and propagating through the ad hoc network. Based on the synchronization, the devices may offer additional functionality and/or more sophisticated applications.
