针对无线传感器网络 WSN 重要技术之一的时间同步技术研究了几种时间同步技术的实现过程。典型同步技术应用于大规模无线传感器网络时鲁棒性和可扩展性受到限制，在此基础上重点研究新的同步技术---协作同步和萤火虫同步。协作同步解决了多跳误差累积的情况；萤火虫同步机制简单，平等对待各个节点，可扩展性和鲁棒性优越。通过对国内外学者的研究成果进行探讨总结，指出了未来时间同步技术的研究重点和方向。

Because time synchronization is one of the important technology of WSN, the realization of time synchronization technology for WSN is summarized. It is concluded that the application of typical technology for large scale WSN is restricted. On this basis, the fireflies synchronization and cooperative synchronization as new technology are researched emphatically. Cooperation synchronization can solve the accumulated error in multi-hop. For treating all nodes equally and easy synchronous mechanism , the scalability and robustness of firefly synchronization are preferable. The future researching direction and focus are also discussed.
