Improvement and Experimental Research on Localization Node Technology in Wireless Sensor Networks
In node localization technology,the search ability of SSO algorithm is imbalanced and the convergence accuracy is low.Therefore,a mixed strategy social spider optimization GSSO algorithm is proposed.Through experiments,compared with SSO algorithm,GSSO algorithm has improved the worst,best,and average coverage by 8.48%,7.81%,and 7.91%,respectively.and compared with the wDESSO algorithm,the coverage of the GSSO algorithm has increased by 2.81%,2.59%,and 2.92%,respectively.This indicates that the GSSO algorithm has good optimization performance,and the average WSN coverage of the GSSO algorithm is higher.In addition,based on the DV Hop algorithm of GSSO,the minimum and maximum positioning errors of unknown nodes are 0.34 m and 13.20 m,respectively,with small positioning errors and high positioning accuracy.
