摘要：Sensor nodes can be used for continuous sensing, location sensing and event detection with the help of different types of sensors such as seismic, thermal, visual, infrared, magnetic, and many gaseous sensors. Sensor networks have wide range of applications including medical, military, home, etc. All these applications involve vigorous wireless communication protocol that is good in reduced energy utilization. A Low Energy Adaptive Clustering Hierarchy (LEACH) algorithm is a protocol designed to obtain energy efficient application specific data aggregation with good performance for the wireless sensor networks. LEACH is a cluster-based routing protocol in which each node has given equal probability to act as cluster head. In this paper, analysis has been done with LEACH protocol and modified LEACH protocols like LEACH-C, and DEEAC. Analyses show that with proper enhancement in the LEACH design, the transmission can enhance the energy efficiency and increase the life time of the sensor node
