Analysis on Enhancements in LEACH Protocol for WSN

Owing to recent technological advancements in wireless sensor and communication technologies, WSN has become a prominent research topic tapping the potential use of it to a wide range of applications. A large quantity of miniscule sensor nodes collaborating and communicating through a wireless medium, collect and propagate data finally to a base station or sink for useful analytical purposes constitutes a WSN. Routing becomes imperative in WSN due to resource constrained nature of the sensor nodes. LEACH (Low Energy Adaptive Clustering Hierarchy) is the most popular and conventional cluster based hierarchical routing protocol which is generally accepted in all its ramifications and its importance cannot be overemphasized.
