Energy Optimization in Wireless Sensor Networks Applications: A Survey

Abstract: A Wireless Sensor Networks (WSNs) are equipped with large number of sensor nodes that consists of several sensing elements distributed to achieve specific objective of environment. Sensor nodes can be used to solve many issues like air pollution, water pollution, wind speed and irrigation of agriculture. Energy is the most important factor in WSNs to enhance the sensor lifetime as well as the network lifetime due to all sensors is battery powered. Future research involves designs the routing protocols to utilize less energy during communication to extending the lifetime of network. In most of the applications, a replacement or rechargeable of energy is more expensive. An energy harvesting wireless sensor networks make use of nodes that are able to get energy from the environment. In this paper, we discuss and review wireless sensor network applications and energy optimization to minimize the e-waste to enrich for environmental. Keywords: Energy, E-Waste, WSN, Energy Harvesting
