Abstract

To synchronize clocks of nodes with low energy use and in short time in WSNs, this paper focuses on the reduction of the number of transmissions and on the message forwarding amongst sensor nodes. And we present a method, which is called EETS (Energy-Efficient Time Synchronization). The EETS method decreases the number of messages for the time synchronization and the messages could be rapidly passed through the network. Additionally, the WSNs are finally able to save energy. Through the performance comparisons of existing algorithms and the EETS with a network simulator and analysis, we show the performance evaluations of the EETS and the improved energy efficiency of the proposed algorithm for the Time Synchronization in the WSNs.
