A COMPARITIVE STUDY OF ENERGY EFFICIENCY IN WIRELESS SENSOR

Wireless Sensor Network is a wide area for the research work. It consists of various sensor nodes. Sensor node has very limited battery power. Batteries are unattended and not possible to recharge them. Small size of a sensor node restricts embedding high power battery with it. Here in this paper we find out the energy efficiency techniques and discuss the main directions to energy conservation in WSNs. Special attention has been given to solutions which have not yet obtained in the survey, such as techniques for energy efficient data acquisition.At last we conclude about the energy efficiency in wireless sensor network.
