摘要
无线传感器网络作为一种全新的信息获取和处理技术,可以在广泛的领域内实现目标监测、信息采集和目标追踪等任务,节点定位问题则是许多应用的基础,是无线传感器网络的支撑技术之一。对基于测距定位算法和免于测距定位算法进行了分析对比,并对无锚节点这一新的节点定位技术做了介绍。最后对节点定位算法的优缺点作了总结,并对节点定位技术未来趋势进行展望。
Wireless sensor network(WSN) as a new information acquisition and processing technology can be widely used within the field of target monitoring,information acquisition and target tracking.Sensor node localization problem is a basis for many applications and one of the support technologies of WSN.The range-based WSN localization algorithm and range-free WSN localization algorithm are analyzed,and a new non-anchor node localization technology is introduced.Finally,the advantages and disadvantages of existing localization algorithm are summarized and the future trend is put forward.
