- Abstract
The positioning technology is of vital importance in Wireless Sensor Networks (WSNs), and its accuracy based on particle swarm optimization (PSO) is low. Therefore, this paper considers the problem of low positioning accuracy and slow speed of convergence by proposing a honeycomb shape localization algorithm based on Levy-PSO. First, the communication distance and ranging error analysis shows that there is an optimal length can improve localization accuracy. Then, the localization area is divided into several honeycomb sub-regions with the optimal length. The unknown node communicates with at least six beacon nodes to ensure the reliability of the results. And these honeycomb sub-regions develop their environmental parameters which are calculated from the least squares fitting method. Last, we develop the PSO algorithm with Levy flight mechanism. The simulation results are show the way this algorithm could improve the positioning accuracy in order to have better stability,
