GWO-LPWSN: Grey Wolf Optimization Algorithm for Node Localization Problem in Wireless Sensor Networks

Algorithm 1

Pseudocode for the GWO [31].
Initialize the Grey Wolf population and algorithm parameters
Evaluate the fitness of each search agent
Initialize the first best solution as ,
Second best solution as and
Third best solution as
While ( number of iteration or stop criteria obtained)
   For
      Update the current search agent position by equation (7)
   End for
   Evaluate the fitness
   Update the coefficient vector , and
   If any better solution then update the best agents , ,
   
End while
   Stop the process and visualize the first best agent found so far
