Visible light communication based optical link for data transmission in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) uses tiny low-power sensor nodes to sense physical phenomena and transmit data using radio frequency (RF) technology which faces some problems in different working environments. The optical wireless communication (OWC) systems such as visible light communication (VLC) are considered as candidates to overcome the problems of existing radio frequency communications. The aim of this paper is to design and implement an optical link to connect sensor nodes and measure the link parameters through experiments.
