Abstract

Abstract: This research work focuses to design optical wireless sensor network (WSN) which is enabled with internet of things service to share sensory information to IOT cloud. Directional media access protocol is used to establish communication link between nodes. To avoid network congestion here in this work an additional receiver is added to receiver side is proposed. Optical wireless communication is one of the most efficient, secure and high speed way of communication for short range applications. Directional MAC protocol used in present work is inspired with existing radio frequency protocol with some changes; data rates can ranges from kbps to thousands mbps and very low power consumption ranges in mW. According to proposed WSN model, first, time-slots are allotted for each node in vicinity and then transmission started and in case of nay prior node available its data is immediately transmitted to secondary receiver unit.
