摘　　要：介绍了用GAINS(global actable intelligent networks)节点搭建无线传感器网络(wireless sensor network,缩写为WSN)时间同步实验平台的过程,并实现了WSN时间同步协议TPSN(timing-sync protocol for sensor networks),详细阐述了组成平台的软硬件。在此基础上,可以进一步研究和开发更复杂的时间同步协议,在实际传感器网络中实现具体应用。The process to construct a wireless sensor network time-synchronization test-bed based on the GAINS （ global actable intelligent networks ） nodes is presented, and the timing-sync protocol for wireless sensor networks （ TPSN ）has been realized. The hardware and software of this test-bed are elaborated in detail. Based on this test-bed, more complex time-synchronization protocols can be further studied and developed for application to practical sensor network.
