Random drift particle swarm optimization(RDPSO) algorithm is presented and applied to RSSI localization algorithm
in order to reduce positioning errors generated by RSSI ranging.In simulation experiments
RSSI localization algorithm based on RDPSO is compared with that based on particle swarm optimization(PSO).Experimental results indicate that RDPSO algorithm is superior to PSO algorithm in optimizing performance
which improves positioning precision of nodes
it is proved that the method has fast convergence speed
good stability and high precision.which is suitable for WSNs node localization problem.
