摘要：WSN's are collection of sensor nodes. Power of these sensor nodes is limited and also increase the lifetime of these sensor nodes. WSN's have limited battery power, limited memory and have limited computational power. It consists various parameters like atmospheric pressure, temperature, humidity and heat all are measure or sense by the sensor networks. Today's WSN's is an emerging field for research. Wireless sensor networks have usage of sensor networks in different areas like military area, health applications, home application, disaster management, sensing environment etc. Routing protocols are the most challenging issue and it increases the lifetime of battery. Hierarchical routing protocol is one of most energy efficient routing protocol. Routing algorithms are divided into different types: direct transmission, hop-to- hop. In wireless sensor networks, two paths are single path routing and multipath routing protocols are used for transfer the data or nodes from source to sink. Leach is the one of most energy efficient routing protocol and increases the lifetime of network. All communication in a network is performed by sensor nodes so the effect of energy depletion occurs which decreases the network lifetime. So to optimize networks lifetime there is a need of highly energy efficient routing protocols. LEACH protocols are energy efficient protocol. The main motive or objective of this paper is to study the various variants of the ROUTING protocols and LEACH protocols which are studied to maximize the lifetime of network and efficient consumption of energy.
