Abstract: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.

Key words:wireless sensor network;test-bed;time-synchronization
