无线传感器网络定位技术研究

节点定位技术是传感器网络关键技术之一,具有十分重要的地位.传感器节点采集到的数据必须结合其位置信息才有意义,没有位置信息的数据几乎没有利用价值.叙述了一些典型定位算法,并将这些定位算法归纳为两大类:Range-based的和Range-free的定位算法.最后,将两类定位算法结合起来提出了值得进一步研究的问题.

Research on localization technology of wireless sensor networks

Node location has an important station and it is one of the key sensor networks technologies.Raw sensor data must be combined with spatial information and the value of the raw data can be increased substantially.Raw data without its position information has less capability.Some typical positioning algorithms are introduced,these positioning algorithms are classified as Range-based and Range-free positioning algorithms.Finally,when two types of location algorithms are combined,some questions being worthy of ...
