Multi-Element Free-Space-Optical Spherical Structures With Intermittent Connectivity Patterns

Due to its high bandwidth spectrum, Free-Space-Optical (FSO) communication has the potential to bridge the capacity gap between backbone fiber links and mobile ad-hoc links, especially in the last-mile. Though FSO can solve the wireless capacity problem, it brings new challenges, like frequent disruption of physical link (Intermittent Connectivity) and the Line of Sight (LOS) requirements. This paper study a spherical FSO structure as a basic building block and examine the effects of such FSO structures to upper layers, especially to TCP behavior for stationary and mobile nodes.
