In recent wireless technology, less energy consumption design and new wireless technologies have produced very important applications for wireless devices. These types of applications cover 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 are 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. LEACH protocol evenly distributes the energy load among the sensors using randomized rotation of cluster-heads. In this paper different variants of LEACH routing protocol are included which are categorized based on following topics: (1) Different methods of cluster head selection (2) Load distribution (3) Reliable (4) Synchronization.Keywords: LEACH, different methods of cluster head selection, load distribution, reliability, synchronizationCite this Article:Ravi Sapariya, Tejas Vasavada.
