无线传感器网络节点定位算法的研究

Research on Node-positioning Algorithms for Wireless Sensors Network

无线传感器网络作为一种全新的信息获取和处理技术,可以在其应用领域内实现大规模的监测和追踪任务,而网络中的节点定位是应用的基础,掌握不同定位算法对不同约束条件的敏感程度是十分必要的,从定位精度、通信开销、节点密度、容错性、对硬件设施的依赖等角度,对节点定位算法进行分析和总结。

As a new information acquisition and processing technology,wireless sensors network can achieve large-scale monitoring and tracking tasks in its application.While the node-positioning is the foundation of the application,it is necessary to master the degree that the algorithms are constrained by different conditions,this paper analyzes and summarizes the algorithms from the view of position accuracy,communication overhead,node density,fault tolerance,dependence on hard facilities and the application of the real-world.
