Multiuser Diversity Scheduling: A New Perspective On The Future Development Of Fso Communications

In this chapter, the multiuser diversity scheduling, as a well-known effective RF technique, is extended to the point-to-multipoint Free-Space Optics (FSO) networks where the data transmission experiences the atmospheric-induced turbulence fading. In particular, the limitations on adapting this method to FSO systems along with their solutions are discussed and addressed. Average throughput and latency performances of different scheduling protocols including Round-Robin, Opportunistic Round-Robin, Select-Max, and best user selection are investigated and compared.
