Abstract
Time synchronization is an important supporting technology for wireless sensor network (WSN). In most existing WSN time synchronization algorithms, timestamp is recorded by software when sending and receiving synchronization messages, which involving synchronization errors like send time and access time. In this paper, a WSN time synchronization algorithm based on SFD is proposed. In the novel algorithm, timestamp of synchronization message is recorded by SFD hardware capture. It can effectively eliminate send time, access time and other synchronization errors. Experiments based on proposed algorithm have been done to verify the effectiveness and time synchronization errors are analyzed.
