基于跳距优化的改进型DV-Hop定位算法
An Improved DV-Hop Algorithm Based on Optimization of One-Hop Distance for Sensor Network Localization
摘要
Abstract
DV-Hop localization algorithm is one of the key technologies of wireless sensor network node localization.The traditional DV-Hop localization algorithm due to the deviation of calculation the number of hops and estimate of one-hop distance,resulting in greater localization errors.In order to reduce the location error,an improved positioning algorithm is proposed.The improved algorithm broadcasts the data using multi communication radius and refines the hops to reduce the location error.When calculating the average hop distance of unknown nodes,,remove the isolated nodes,introduce weighted normalization processing,to obtain a more precise one-hop distance.The simulation result indicates that the improved algorithm can greatly improve the location accuracy without obviously increasing algorithm complexity and communication traffic.关键词
