摘　　要：为了解决工业无线传感网覆盖过程中通信半径跳距离产生偏差过大的问题,设计了一种基于GA-TS搜索算法的节点定位方法,并开展仿真分析。研究结果表明,当通信半径不断增大后,算法误差产生不同程度的减少。与传统最大似然估计定位算法相比,GA-TS搜索算法的优化效果更佳,误差大概缩减30%;与移动锚节点算法相比,误差大概降低至15%。相比较之下GA-TS搜索算法定位精度误差最小,具有很大的应用准确性和适应范围。该研究有助于工业无线传感网定位精度,对保证网络信号的传输效率具有一定的意义。In order to solve the problem of large deviation of communication radius hopping distance in the process of industrial wireless sensor network coverage,a node positioning method based on GA-TS search algorithm is designed and simulation analysis is carried out.The research results show that the algorithm error produces different degrees of reduction when the communication radius is increasing.Compared with the traditional maximum likelihood estimation localisation algorithm,the GA-TS search algorithm is better optimised,with the error reduced by roughly 30%;compared with the mobile anchor node algorithm,the error is reduced to roughly 15%.In comparison the GA-TS search algorithm has the smallest error in positioning accuracy and has great application accuracy and adaptability.This research helps the industrial wireless sensor network positioning accuracy,and has certain significance in ensuring the transmission efficiency of the network signals.
