Optical wireless networks often require more than one transmitter to maintain consistent connection with a single receiver. Accordingly, an efficient control mechanism is required to address challenges associated with multiple access to the receiver. This paper proposes a receiver access control (RAC) mechanism for optical wireless mesh networks that focuses on the optimization of classical RTS/CTS...
Pointing, acquisition and tracking of a free-space optical node in a mobile network experiencing misalignment due to adverse factors including vibration, motion and atmospheric turbulence requires a different approach than traditional free-space optical transceivers. A recent fiber-bundle approach for beam steering at the transmitter was investigated to provide continuous beam coverage at the receiver...
