Energy Conservation Schemes of Wireless Sensor Networks for IoT Applications: A Survey

The wireless sensor networks are formed from the network of sensors capable of sensing the physical phenomenon around like heat, light, motion, temperature, humidity, pressure etc. Sensors are tiny shape and deployed in mostly remote areas. The journey of data in the form of packets from the sensor mote to sink underwent many challenges. Huge research is carried to efficiently path the information and utilize the energy judiciously. Sensing, transmitting and receiving the packets and route it to the sink requires high range of power consumption. So, in recent times research is booming in the area of energy saving mechanisms. In the present paper we describe recent researches and classifications of the energy saving techniques of wireless sensor networks like unequal clustering, data acquisition through mobile sinks, energy efficient routing protocols.
