Abstract

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.

Notes

  1. 1.

    The intensity scintillation index or the normalized variance of intensity fluctuations is one of the major parameters in analyzing the effect of the atmospheric turbulence-induced fading on the emitted beam.

  2. 2.

    In the RRS scheme, all users are served in a round-robin fashion and through assigning the same time allocation regardless of the channel gain between the central node and each user.
