基于遗传模拟退火优化的DV-Hop定位算法
Dv-Hop localization algorithm based on genetic simulated annealing optimization in wireless sensor network
摘要
Abstract
In order to further improve the positioning accuracy of WSN,an improved dv-hop positioning optimization algorithm based on genetic simulated annealing method was proposed.Firstly,the number of hops adjustment factor was introduced to correct the number of hops information between nodes.After the introduction of collinearity,the beacon nodes with large errors were removed.Then the average hop distance of dv-hop beacon nodes was optimized by weighting method,which reduced the localization error caused by the limitations of dv-hop algorithm.Secondly,the local search ability of genetic algorithm was enhanced by combining genetic algorithm with simulated annealing algorithm.Simulation results show that DGSA algorithm is more accurate than other localization algorithms in the same situation.关键词
