Abstract :
A method of combining broadcasting TPSN synchronization protocol with node local clock self-correction is proposed through analyzing the nature of TPSN synchronization protocol and star-structure network, aiming at the low energy consumption of wireless sensor network and the accuracy which it requires to clock synchronization. Experimental results show that the method may prolong synchronization cycle while guarantee synchronization accuracy, and decrease the number of network synchronization packages, therefore significantly lower synchronization maintenance cost and save energy consumption.
