Three Dimensional Free Space Optical Network Reconfiguration Heuristics Using Active Link Removal

摘要

Free Space Optical (FSO) communication is a type of optical communication that relying on beams of light to transmit data over long distances wirelessly. With recent increase in popularity of the technology in commercial applications as well as military and scientific applications, it is important to study new models and algorithms to improve the performance of this technology. One of the most important aspects of FSO network is the line-of-sight (LOS) requirement to sustain an uninterrupted data flow. In order to ensure a steady connection, auto-aligning transceivers can be implemented to overcome the LOS issue. In this paper, we propose several re-alignment algorithms to reconfigure a FSO network when there is a loss of line of sight. The main idea of our experiment is to expand up on the three dimensional FSO network model proposed by Kosumo et al. in 2013, addressing cases that have not been considered.
