This paper focuses on an in-depth study of energy efficient-routing in ad hoc wireless network. Since the nodes are powered by batteries with limited capacity, energy management of a node and whole network is a critical issue in ad hoc wireless networks. Energy management is an optimization technique, used to maximize the operational lifetime of networks through energy-efficient routing. Various energy efficient routing algorithms are proposed for ad hoc network to improve the life time of network by considering the various parameters such as remaining battery energy, link quality, etc. LEACH is an energy efficient hierarchical based protocol that balances the energy expenses, saves the node energy and hence to prolongs the lifetime of the network. So this paper presents a detailed review and analysis of LEACH protocol. Comparison of the various networks parameters is done in the form of tables and graphs. The simulation of the work has been carried out by using own set of parameters and in the last of the paper conclusions is drawn.
