Conservation of energy by using grid clustering in wireless sensor networks

Wireless sensor networks are the networks that have small network sensor nodes. They are used now days in order to monitor borders, pressure, temperature, weather forecasting. These sensor nodes need rechargeable battery for the power supply. The main disadvantage of these networks is that they have limited power supply. As these sensor nodes are used at borders where battery backup are limited, due to which energy is consumed. So to optimize energy, clustering is used in wireless sensor networks to increase the network lifetime of sensor nodes. In this paper our main concentration is on grid clustering for the energy optimization of sensor nodes. In this grids are further divided into small grids in order to reduce the energy consumption. Size of grid is directly related to the transmission range of the nodes. So as the size decreases the transmission range also decreases, this in turn conserves the energy.
