A Review of some LEACH Optimization Protocols for Wireless Sensor Network Clustering

The range of using wireless sensor networks is very wide as its application includes most fields. Because of the impact of communication costs on node power consumption, this sort of network has restricted node capacity and a short lifespan. Sensor nodes in wireless sensor networks rely on their mostly non-rechargeable batteries to monitor, collect information and send it back to the Sink, via various techniques for routing. remarkably efficient and extensively used routing protocol is LEACH. as it is based on a hierarchical grouping of nodes. However, it suffers from some drawbacks. In this article, we attempt to address the LEACH protocol and a comparative presentation of some of the improvements that have come in the literature. Finally, we offer proposals for enhancing this technique.
