A joint passive time synchronization and localization algorithm for underwater silent mobile node

Abstract

Underwater Acoustic Sensor Network(UASN) is an emerging Marine information collection technology. When a mobile node (MN) joins a fixed UASN (the clock of the anchor nodes (ANs) in UASN is accurate and the location is known). After a period of sailing, clock drift would cause out-sync which affects the positioning, navigation and other services of MN. Thus, the development of elimination method for clock drift in UASN is imperative.
