Clock Synchronization for Wireless Sensor Networks Based on Time-stamp

To implement synchronization for the wireless sensor networks with indirect connectivity,the clock synchronization mechanism for wireless sensor networks was thoroughly analyzed.A kind of clock synchronization algorithm based on time-stamp scheme was presented.Then it was studied and evaluated in detail.Experiments indicated that the proposed clock synchronization algorithm based on timestamp was energy-effective,which was able to obtain a synchronization precision of one millisecond in order of magnitude,which can satisfy most of the practical applications of wireless sensor networks.
