An analysis of LEACH Protocol in Wireless Sensor Network: A Survey
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2015, Vol 6, Issue 3
Abstract
Wireless Sensor Network is composed of numbers of tiny sensors (nodes) which have the capability of gathering the data about environmental activities and making certain computations on them so that they can be communicated to the next node & finally to the Base Station. All the sensors work in co-ordination with each other to make communication successful. These sensors have to be continuously in active mode in order to receive and transmit data which increases their energy requirement. As these sensors are battery-powered, this continuous monitoring activity reduces their lifespan. Efficient management of energy is a critical requirement for the optimal design of a wireless sensor network. Thus, a protocol is critically needed that can make the wireless sensor network energy efficient. In this paper a detailed view and analysis of LEACH Protocol will be discussed. LEACH Protocol is a cluster-based hierarchical protocol which creates an energy balance in the network, saves the node energy and hence increases the lifetime of the network.
