A SURVEY ON ENERGY OPTIMIZATION IN WIRELESS SENSOR NETWORK

Wireless sensor network is one of the emerging technology which provides a wider range of applications like monitoring pressure, temperature water level, minerals in soil, health care etc. Generally, this network is a collection of small sensors which can sense, process and communicate the data, based on the specified application. The major constraint of this type of network is the energy consumption by the sensor nodes which is mainly responsible for the prolonging the lifetime of the network. A limited amount of energy should be utilized very efficiently so that the life of a network can be prolonged. The first section of the paper presents brief introduction about wireless sensor network and its basic features and also about the concept of clustering with its applications. The next section briefly describes about energy consumption factors in the wireless sensor network and how the energy can be utilized efficiently and effectively to prolong the life time of the network.
