Research on Node Localisation of Industrial Wireless Sensor Network Based on GA-TS Search Algorithm
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.
