A Survey on Different Approaches for Energy Conservation in Wireless Sensor Networks

In the recent years the applications of wireless sensor network s in the fields such as scientific, military and healthcare have developed . So it has gained more attention in research area. A sensor node is basically a battery powered device and the use of battery has become a constraints. The main motive is to reduce the energy consumption of sensor node to increase the network lifetime. In t his paper, we have discuss ed about the energy consumption of a particular sensor node of WSNs. Then we have represent ed various systematic and comprehensive schemes of energy conservation, which are subsequently discussed in depth. Special attention has been given to the literature survey a nd devotion of promising sol utions faced in each technique. We have provided some solutions that are being faced in each technique. In the final part we will look into the different directions for research about energy conservation of wireless sensor netwo rks
