Abstract

Wireless sensor networks (WSNs) are networks formed by a large number of electronic devices called sensor nodes, where each node is capable of measuring environmental or physical values and communicating data, through wireless links, to a base station. The main problem that WSNs routing protocols face, is that sensors are powered with low power batteries, which plays an important role in network lifetime. Low Energy Adaptive Clustering Hierarchy (LEACH) is a hierarchical cluster based routing protocol that was proposed as a solution for low power consumption in WSNs. One of LEACH protocol limitations is “Extra Transmissions”. This paper studies LEACH protocol, some of its various enhancements and finally proposes a new clustering and selecting cluster head scheme with the goal of optimizing the energy consumption in WSNs.
