Abstract
Time synchronization is a critical component in any wireless sensor network (WSN).This paper describes a new protocol based on data analysis, referred to as Global Time Synchronization (GTS), for synchronizing the clocks of a wireless sensor network. This algorithm is based on a cascade of two different algorithms to deal with the global time adjustment; one solves the problem of efficiency, another solves the problem of accuracy. Currently existing time synchronization protocols have a very low accuracy and very strong spatial accumulative effect. These features are not suitable for several types of WSN applications, such as applications with stringent temporal requirements, or applications that have a large spatial region of interest. We use analysis and simulation results to prove the correction of the protocol.
