Enhanced Logical Tree based Routing for Energy Efficient Wireless Sensor Networks

Abstract- Advances in sensor networks provide the opportunity for wide range of applications. But there are many limitations like energy constraints, communication limitations and sensor node failures. Out of these the primary challenge is energy limitation and prolonging the network lifetime especially for sensors deployed in environments like battlefield surveillance, weather monitoring, disaster management that are not easily accessible. To overcome these limitations, several solutions have been proposed. In this proposed work, enhanced logical tree based routing protocol is proposed to enhance the lifetime of the sensor networks. By simulation results the proposed ELTRP (Enhanced logical tree based routing protocol) effectively reduces and balances the energy consumption among the nodes and thus significantly extends the network lifetime. The proposed technique outperforms previous method in terms of energy efficiency and network life time. Index terms- energy efficient, tree, network lifetime, wireles
