无线传感器网络的节点自定位技术

文章对无线传感器网络的节点定位机制与算法进行了介绍,并对基于测距的和不基于测距的两大类方法进行了分析对比.文章认为节点定位是无线传感器网络的一项关键技术,对于无线传感器网络的许多应用来说节点位置信息都是必须的基本信息,虽然目前已有不少节点定位技术,但仅仅是一些初步的研究成果,距离无线传感器网络的整体优化目标还很不够,需要继续深入研究开发,提出更多的高效算法,促进无线传感器网络进一步的普及应用.

Self-localization Technologies for Wireless Sensor Network Nodes

The paper introduces the self-localization mechanism and some algorithms for Wireless Sensor Network (WSN). Moreover, it analyzes and compares the range-based and range-free localization algorithms. It thinks that node location is a key technology for WSN and the information about node location is indispensable to many applications of WSM. Existing node location technologies are the primary research achievements, which are far from the goal of the whole WSN optimization. Therefore, further research and development of more high-efficient algorithms is necessary for popularization of WSN applications.
