Abstract: The Wireless Sensor Networks are used today to monitor hostile environments where the reach of human is not possible. For monitoring purposes in WSN, sensors are used that has capabilities of sensing, processing data and revelating the processed data to other sensors or surface station. To sense data in routing, data agglomeration and energy efficient protocols are designed for WSN as energy consumption is a serious issue in this network and thus after sensing data routing this data to destination is the main motive during the network. Hierarchical routing comes into existence that proves to be promising approach for point to point routing with a very small state of routing. Here in this paper, AODV routing is simulated for hierarchical routing in order to demonstrate its further use for realistic applications and WSN’s setting. In this paper, the energy is very less consumed while having countable sets of sensors nearby for revelating data. At the end of the simulation, energy is saved and the connection with shortest distance comes out to be a lucrative result. In this paper, the state of art of AODV is presented by taking into deliberation of the topology changes during the energy depletion and node failure.
