Research and application of synchronization compensation mechanism in wireless sensor networks

Among the wireless sensor network applications which are triggered by events and with some of the nodes synchronization,the traditional periodic time synchronization algorithm for the entire network synchronized will lead to unnecessary power consumption.Therefore,this paper analyzed the existing time synchronization mechanism,and proposed a time synchronization compensation algorithm based on event-triggering for such applications.Moreover,the algorithm achieved synchronization through the statistics accumulated along the processing delay and propagation delay compensation.The experimental results show that the synchronization algorithm has good performance and energy efficiency when the interested nodes number and events frequency are low.
