Energy Efficiency Improvement in LEACH Protocol for Wireless Sensor Network

Abstract

The most important reason for saving energy on wireless sensor networks is communication. Data transmission consumes about 70% of the energy of the sensor node. Effective use of energy on sensor nodes is a good way to increase the lifetime of WSN. In order to extend the life of the network, energy-saving routing protocols must be designed. In this article, I will discuss (LEACH), which is the first and most popular energy-saving hierarchical clustering algorithm for WSN and an improvement to Leach and VLeach that attempts to eliminate the shortcoming of V-LEACH and LEACH protocols, In this method, initially, the “sub-cluster head” and “cluster head” are selected according to the energy and distance parameters. The head of the cluster and the vice president of the cluster make decisions based on the distance and the remaining energy of the sensor nodes. Compared with standard leaching, this algorithm can provide better network life, efficiency and performance.
