Wirelessly Synchronized One-Way Ranging Algorithm With Active Mobile Nodes

Free registration required

Executive Summary

In this paper, the authors propose a one-way ranging algorithm that is based on wireless synchronization with measured timestamps and clock frequency offsets. In their proposed algorithm, an active mobile node initiates a ranging procedure by transmitting a ranging frame, and the anchor nodes report their timestamps for the received ranging frame to a reference anchor node. The synchronization of a pair of nodes is provided with instantaneous time information, and the corresponding difference of distances can be calculated.
