基于DV-Hop测距修正的遗传模拟退火定位算法
Improved DV-Hop Ranging-Based Genetic-Simulated Annealing Localization Algorithm in Wireless Sensor Networks
摘要
Abstract
In order to improve the localization accuracy of DV-Hop in Wireless Sensor Networks( WSNs) ,Improved DV-Hop Ranging-based Genetic-Simulated Annealing Localization ( IDV-Hop-GSAL ) algorithm is proposed in this paper. IDV-Hop-GSAL introduced Near-degree,and modified the ranging by DV-Hop. Then the original position of unknown nodes is obtained by least squares method. Finally,the most optimal solution to obtain a position of un-known nodes is achieved with the help of GASA optimization algorithm. Numerous simulation results show that aver-age localization error ratio of IDV-Hop-GSAL algorithm is less than that of traditional DV-Hop algorithm.关键词
