A Review of Wireless Charging Nodes in Wireless Sensor Networks

Sensing of data and computation properties of sensors has created a new group of these type devices and to the using more of these types of sensor devices which are established in wireless sensor networks (WSNs). Wireless sensor networks customized sensor nodes which are situated in open areas as well as public places, with a large number that makes some problems for the scholars and designer, for designing the wireless network. There are problems such as security, routing of data and processing of bulk amount of data, etc., and life time of sensor nodes due to limited battery power, charging and replacement of batteries are sometimes not possible. This paper describes the concepts of wireless charging of sensors nodes with energy-efficient manner in WSN. We explore the concepts of wireless charging node in WSN with detail literature review and comparison of well-known works. It helps to new scholar to get decision in existing techniques and more explore about energy transfer to the sensor nodes in wireless sensor network.
