在很多无线传感器网络应用中，没有节点位置信息的监测信息往往毫无意义。当监测到事件发生时，关心的一个重要问题就是该事件发生的位置，如森林火灾监测，天然气管道泄漏监测等。这些事件的发生，首先需要知道的就是自身的地理位置信息。定位信息除了用来报告事件发生的地点外，还可用于目标跟踪、目标轨迹预测、协助路由以及网络拓扑管理等
In many wireless sensor network applications, there is no node location information of the monitoring information is often meaningless. When monitoring the event occurs, an important issue of concern is the location of the incident, such as forest fire monitoring, natural gas pipeline leak monitoring.
