Abstract: Wireless Sensor Network are in great demand from the recent years, as nowadays we have seen a wide growth of wireless devices including cellular phones, laptops, mobiles, PDA’s etc. Wireless Sensor Networks consists of thousands of tiny sensor nodes. In a wireless sensor network a node is no longer useful when its battery dies, so to avoid this problem many routing protocols were introduced. Wireless sensor network is a collection of a large number of small nodes which acts as routers also. These nodes carry very limited power source which is non-rechargeable and non- replaceable which makes energy consumption an significant issue. Energy conservation is a very important issue for prolonging the lifetime of the network. As the sensor nodes act like routers as well, the determination of routing technique plays a key role in controlling the consumption of energy. This paper describes the framework of wireless sensor network and the analysis and study of various research work related to Energy Efficient Routing Protocols like LEACH “Low-Energy Adaptive Clustering Hierarchy”, PEGASIS “Power-Efficient Gathering in Sensor Information Systems”, TEEN “Threshold sensitive Energy Efficient sensor Network protocol”, and their comparion.
