Sensing and detecting of the events through sensor networks is one of popular research areas. Sensors can help us not only to detect the pollution, but also to monitor the environment that is beyond our reach. When sensor nodes go on their missions, synchronization is a very important issue. If the clock in the all sensors is not synchronized, as they detect the event and send the data to the sink in the sensor network, the sequence of data with time stamp will be disorder. It is harder to read and identify data. Prior to our research, there are a lot of methods to synchronize all nodes in the sensor network, for example, Lightweight time synchronization for sensor networks (LTS), centralized multi-hop lightweight tree-based synchronization (CLTS), pulse-coupled, cluster-header and so on. The methods between the pulse-coupled and cluster-header have the same characters. When the sensor networks are synchronizing, the nodes in the pulse-coupled way and the cluster-header method will provide their own information to sync each other. In present study, we will compare the different between the pulse-coupled method and the cluster-header method.
