无线传感器网络中基于反距离加权的DV-Hop改进算法
Study on Improved DV-Hop Algorithm Based on Inverse Distance Weighting Method in Wireless Sensor Networks
摘要
Abstract
An improved algorithm was proposed by analyzing the deficiencies of traditional DV-Hop algorithm in terms of ran-dom distribution, which owns improvements over two aspects.Firstly, instead of variance or deviation, the average one-hop dis-tance is estimated by minimum mean-squared error criterion (MMSE).Secondly, in order to reflect the different effects of each beacon node on unknown nodes, inverse distance weighting method is adopted to deal with the average one-hop distance.Improved algorithm is simulated on MATLAB platform , and the results show that the positioning accuracy is improved on the condition of no increasing complexity and cost.The improved algorithm is a simple and practical algorithm.关键词
