摘要：Wireless Sensor Network (WSN) comprises a large number of homogeneous or heterogeneous nodes having capabilities of sensing, computation and to communicate wirelessly with each other. They are used for continuous monitoring of various civil and military applications. Nodes in the WSN are battery powered, so energy is the main constraint while designing a network. In this paper, we present a survey on Low Energy Adaptive Clustering Hierarchy (LEACH) protocol and its various variant. These communication protocols make use of adaptive clustering techniques which help in reducing overall energy consumption of the network. LEACH protocol utilizes the randomized rotation of cluster heads to distribute the energy load among all the nodes in the sensor networks. LEACH uses localized coordination for strengthening of network and blend data fusion into routing protocol to lower the amount of information that is to be transmitted to the base station. LEACH provides better energy efficiency than the conventional routing protocols.
