An Improved Energy Efficiency Algorithm in Wireless Sensor Network Using Query Optimization

Wireless Sensor Networks (WSN) is an essential guide foe anyone interested in wireless communications for sensor networks, home networking, environment monitoring, target tracking, and surveillance. In wireless sensor network sensor nodes have very limited supply of energy, and also should be available in function for extremely long time (e.g. a couple of years) without being recharged. So consider the energy resource of sensor node and the life time of the sensors, to optimize the query plan, based on user specified accuracy for wireless sensor network. This proposed method aims at optimization of periodical query, with careful consideration of accuracy, along with energy consumption in data communication. User may specify a value/time accuracy constraint, according to which an optimized query plan can be created to minimize the energy consumption. The main objective is to propose an energy efficient algorithm to reduce data transmission and to increase the life time of wireless sensor network.
