A Review: Energy Efficiency using Various Protocols in Wireless Sensor Networks

An operative and manageable network is always required to fulfill the many practical applications ranges from small scale industry to large scale power conserved environment tracking. In case of wireless sensor networks (WSNs), energy devastation of network node is a tremendous confrontation in the context of maximizing the lifetime span of the WSN. It will always be risky, very costly or in some cases even impossible to charge or replace the overexerted batteries because of the contentious nature of the network. There are many researches for designing energy efficient protocols while as actualizing the desirable WSN operation. We are focusing on many different schemes which are used to degrade the energy utilization factor of the sensing nodes. When we diagnosed the causes for energy dissipation by the nodes, we are able to classify energy efficient schemes such as topology control, duty cycling, control reduction, energy efficient routing and data reduction.
