Abstract

A new spread-spcetrum-based synchronization and geolocation method is presented. The synchronization method is based on determining the round-trip time between nodes. By using a spread-spectrum technique, delays of processing handshaking messages and switching transceivers from receiving mode to sending mode do not incur any inaccuracy. The geolocation method integrates our synchronization technique with the triangulation method, which is commonplace in geolocation systems. This new synchronization and geolocation method provides a cheap, efficient, and effective way to synchronize nodes and render location information in a wireless environment.
