A Review of Energy Conservation in Wireless Sensor Networks

Bolaji Omodunbi, O.T. Arulogun, J.O. Emuoyibofarhe


In wireless sensor networks, energy efficiency plays a major role to determine the lifetime of the network. The network is usually powered by a battery which is hard to recharge. Hence, one major challenge in wireless sensor networks is the issue of how to extend the lifetime of sensors to improve the efficiency. In order to reduce the rate at which the network consumes energy, researchers have come up with energy conservation techniques, schemes and protocols to solve the problem. This paper presents a brief overview of wireless sensor networks, outlines some causes of its energy loss and some energy conservation schemes based on existing techniques used in solving the problem of power management.

Keywords: Wireless sensor network, Energy conservation, Duty cycling and Energy efficiency.
