Free Space Optical Networks: A Survey
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 12
Abstract
Optical wireless networks, also known as Free Space Optical (FSO) networks have emerged as a promising solution for future high speed networks, and for broadband wireless communications. The range of the potential application of FSO networks is very vast, from home to satellite. FSO is in very much demand because of their ability to efficiently manage network resources, and it provides better spectrum utilization to fulfill with the rapid change in traffic behavior and the huge growth in bandwidth demand. However, these FSO networks have not been much popularized because of insufficient reliability and availability. Researchers have focused on the problems in the physical layer to get benefit of the properties of wireless optical channels. And also, the recent technological developments with successful results makes it possible to explore the advantages of the large bandwidth. The problems of network and upper layers in optical wireless networks attracted the attention of researchers. In this paper, we present a study on global FSO networks and will discuss what kinds of challenges exist in this area.
