无线传感器网络节点定位算法的研究与改进

Research and Improvement of Localization Algorithms for Wireless Sensor Networks

针对无线传感器网络中DV-Hop定位算法的不足,在其基础上提出三种改进的定位算法,并介绍每种算法的基本原理和实现方法。在同一仿真平台上进行比较,分析三种改进算法在锚节点比率不同的情况下,对定位误差和覆盖率的影响。仿真结果证明了改进算法的有效性。

To overcome the disadvantage of DV-Hop algorithm,three improved algorithms are proposed based on the characteristics of DV-Hop,the basic principles and the implementing approaches of the algorithm are introduced. And location algorithms on a single simulation platform are compared. On analyzing the three algorithms in different ratio scenarios of anchor nodes,the effect of the localization error and localization coverage of anchor nodes can be confirmed. Through the analysis and comparison,and simulation results proved their validity.
