A Survey on the Energy Efficient Protocols in Wireless Sensor Networks

Abstract

Wireless sensor networks are formed by deployment of numerous sensor nodes on a wide area. These sensor nodes are limited in energy supply and bandwidth which pose many challenges in maintenance of sensor networks. Thus, intelligent usage of available energy through optimal route setup and reliable data transmission across sensor networks is vital in order to maximize lifetime of the network. This paper gives an overview of various routing protocols based on energy efficiency and QoS through which optimal data exchange is carried out in wireless sensor networks.
