Synchronous Firefly Algorithm for Cluster Head Selection in WSN

Algorithm 1

Pseudocode for cluster formation and CH selection in firefly.

Objective function , = ()

  Generate initial population of fireflies (

  Light intensity at is determined by

  Define light absorption coefficient

  while ()

  for all fireflies

  for all fireflies

  if (), Move firefly towards in -dimension; end if

  Attractiveness varies with distance via

  Evaluate new solutions and update light intensity

  end for

  end for

  Rank the fireflies and find the current best

  end while
