Optical Wireless Communication and Recharging Mechanism of Wireless Sensor Network by Using CCRs
Broad spectrum of optical wireless communication is available, which can fulfill the requirements of high speed wireless communication. This is the basic advantage of optical wireless communication over conventional wireless communication technologies. The other important thing is the day by day decreasing size of wireless sensors with the advent of advancement in device processing technologies like micro- and nano-electromechanical systems. This decrease in dimensions of sensors causes serious problem for battery storage capacity. They address this issue and propose a model of communication and recharging of Wireless Sensor Network (WSN) nodes simultaneously using passive optical communication. The authors propose both Line-of-Sight and Quasi-diffuse communication for this purpose.
