A Literature Survey of Energy-Efficient clustering in WSN using Different Variant of LEACH Routing Protocol

In Recent Wireless Technology, Less Energy Consumption Design and New Wireless Technologies have Produced Very Important Applications for Wireless Devices. These Type of Application Covers Very Large Area and also Use for Real Time Transfer of Large Data from one Device to Another, Due to this Kind of Application WSN Generally Suffering from Resource Constraints. Nodes are General Battery Powered. This Makes Application with Limited Energy so it is Very Critical to Operate Sensor Network for a Long Time. Data Aggregation is a Technique in which Data are collected from multiple sources and expressed in compressed form. This Compressed form is nothing but summary of collected data. The amount of traffic will reduce due to data aggregation. Hierarchical-based Routing Protocol is efficient and absolute Solution to this Problem. LEACH is Hierarchical-based Clustering Routing Protocol that utilizes Randomized Rotation of Cluster-Heads to evenly distribute the Energy Load among the Sensors in the Network. In this paper Different Variant of LEACH routing Protocol are included which are Categorized Base on following Topics: (1) Different Method of Cluster Head Selection (2) Load Distribution (3) Reliable (4) Synchronization.
