A localization algorithm based on wireless sensor networks in long and narrow space
Through laboratory corridor testing experiments,it was found that using symmetric averaging could greatly improve the linear relationship between RSSI values and distance.Based on this,a symmetric non-uniform deployment method and positioning method were proposed.Finally,MATLAB simulation experiments and analysis were conducted on this positioning method.The simulation experiment results showed that compared with traditional positioning methods,the average positioning of error this method was 4～6 m smaller.With high positioning accuracy,it was less affected by the environment,suitable for narrow and long spaces such as underground tunnels and ultra long tunnels.
