Energy efficient routing mechanism in Wireless Sensor Network

This paper gives a brief idea about wireless sensor networks and energy efficient routing in wireless sensor networks. Sensor networks are deployed in an ad hoc fashion, with individual nodes remaining largely inactive for long periods of time, but then becoming suddenly active when something is detected. Sensor Networks are generally battery constrained. They are prone to failure, and therefore the sensor network topology changes frequently. In this paper, we propose a routing algorithm for Wireless Sensor Networks combining Energy Efficient and Hierarchical based routing techniques which minimize the energy consumption, increase the lifetime of the sensor nodes and saves battery power.
