A Review on Energy Harvesting in Wireless Sensor Networks

Wireless sensor networks (WSN) are generally distributed independent sensors which work mutually to monitor all or some physical or ecological conditions, such as temperature sound, pressure, moisture, humidity etc. They are sometimes called as Wireless Sensors and Actuators Networks (WSAN) as well. Wireless Sensor Networks work thoughtfully to pass their information through the network by capable routing to a main location or base station. The more recent networks are generally bi-directional; also enable the control of sensor activity. The development of wireless sensor networks was primarily aggravated by military applications such as Warfield surveillance, battlefield surveillance; today such wireless sensor networks are used in several industrial, consumer and medical applications, such as machine health monitoring and control, industrial process machine monitoring and control, , and so on. In this paper, concise review is presented of protocols in wireless sensor network for energy harvesting.
