Guoqing Chen · Computer Technology and Development · 2012
With the rapid development of the wireless sensor network,the time synchronization plays an important role.For the wide coverage and low power consumption of the WSN,how to reduce energy consumption as soon as possible while ensuring the accuracy of time synchronization becomes a problem to be solved.It gives a detailed analysis of the category,characteristics and functions of the clock synchronization technology in the wireless sensor network(WSN),the time synchronization technical plan is presented.This method establishes the topological structure firstly,applies the LEACH algorithm,combined TPSN algorithm and RBS algorithm,conducts the time synchronization in the global scope.The results show that this method has less energy consumption and a close synchronous precision to TPSN.
