Research on Time Synchronization in Wireless Sensor Networks
In Wireless Sensor Networks, time synchronization is necessary. Some intrinsic properties of sensor networks, such as limited resources of energy, storage, computation, and bandwidth, make traditional time synchronization methods unsuitable for WSN. This article formulates the time synchronization problem and the need for synchronization in sensor networks ,and also introduces some time synchronization algorithms , and make further research on the ideas of "carry time information with mobility of the nodes" when taking mobility into account, which is proved to be good by simulation.
