An Energy-Efficient Time Synchronization Algorithm for Wireless Sensor Networks

An energy-efficient time synchronization(EETS) algorithm is proposed,and error prediction and compensation mechanism are employed to decrease the accumulative error between nodes.By this method,the synchronization cycle of wireless networks nodes can be adjusted dynamically according to the user requirements in terms of time synchronization precision,so as to achieve the maximum time synchronization cycle under the given error precision and lower time synchronization overhead.
