Improving the energy efficiency of wireless sensor network through wireless energy transfer

Abstract

With the recent development in the communication field wireless sensor plays a decisive role in various application areas like medicine mechanical engineering embedded technology agriculture military etc The demand for sensor is rapidly growing day by day Wireless sensor networks are formed by collection of network of autonomous nodes which have been employed in a wide variety of applications As sensor nodes are battery powered guaranteeing the energy supply for long time has persisted as a big challenge to the sensor node lifetime The wireless energy transfer has been a recent emerging technology in wireless sensor network This technology is a promising alternative to the power constraint problem in wireless sensor network Energy is the important constraint in a sensor network which can be improved by different technologies Energy harvesting techniques can scavenge some amount of energy but still it s not enough Lots of researchers put effort to solve this problem which results in a wireless energy transfer In this technology wireless charging vehicle travels along a pre-planned path in the sensor network Our goal is to minimize energy consumption of the entire network while ensuring that each sensor node is supplied the required energy by charging without the node dead. newline
