ESO-LEACH: PSO based energy efficient clustering in LEACH

open access: yesJournal of King Saud University - Computer and Information Sciences, 2021
Low Energy Adaptive Clustering Hierarchy (LEACH) algorithm has various demerits like picking of cluster head during each round which depletes energy of the node, non consideration of residual energy to name a few. Due to this, researchers are focusing on ways to boost the LEACH algorithm and making it more efficient for practical use.
