Hybrid RF/FSO, Wireless Optical, Topology Control, RF, FSO, Linear Programming
In this article, we describe the limitations of radio frequency (RF) and Free Space Optics (FSO) technologies, and show that a hybrid approach that uses both communication media in a suitably coordinated manner is capable of addressing the shortcomings of each. The nature of the required coordination between RF and FSO communication technologies, and the merits derived thereof, are the subject of our research. We report on an initial hardware implementation of a prototype Hybrid RF/FSO node. The properties of the node are used to inform the development of an Integer Linear Programming (ILP) model for this coordination process in RF/FSO networks. We show that by making suitable choices of beam-widths and power levels, the proposed model can be used to design robust hybrid RF/FSO communication infrastructures that minimize power consumption, while satisfying specified joint throughput and end-to-end delay requirements.
