LEACH based protocols: A survey

Abstract

Advances in the world of communications and information technology, as well as the urgent necessity to monitor particular areas and regions, have led to a considerable and influential development in the world of wireless sensor nodes. As they are small, low-cost multipurpose nodes with limited energy and capabilities. The most important points that deserve research and solution is the problem of energy conservation and increasing the lifetime of the network as a whole. Whereas, many routing protocols have been proposed in the wireless sensor network, some of which are based on homogenous networks while others are not, some are location-based, some are based on hierarchical orientation, some are based on the hybrid approach and many more. Despite the long time that has passed since the discovery and activation of the Low Energy Adaptive Clustering Hierarchy (LEACH) protocol, it and its descendants still have the lion's share of attention, research, and development. In this research, we will be presenting the most prominent routing protocols while pointing to some pros and cons of each protocol.
