Intelligent Wireless Sensor Network using Low Space free space optical communication sensor networks

Abstract

The free space optical communication sensor networks (FSOSN) have shown impending, for very low power, energy aware applications. They aptitude increasing node functionality, lower energy consumption, lower cost and smaller sizes. However, the new wireless sensor network architecture yields new challenges. FSO can be explained by the means to the transmission of modulated visible or infrared (IR) beams through the atmosphere to obtain broadband communications over distances of several kilometers. The main constraint of FSO is the requirement that a direct line-of-sight (LOS) path exist between two parties the sender and a receiver. However FSO networks offer several unique advantages over RF networks. The fact that include by FSO that it avoids interference with existing RF communications infrastructure is competitively deployed since there is no government licensing of scarce spectrum required, is not susceptible to ?jamming? attacks, and provides a convenient bridge between the sensor network and the nearest optical fiber. The main aim of this research is to develop a low power free space optical communication based intelligent wireless sensor network on 8-bit microcontroller which enables integration of existing devices easily using off the shelf components.
