Resilient Architectures for Free Space Optical Wireless Interconnection Systems
Sanaa Hamid Mohamed, Osama Zwaid Alsulami, Taisir E. H. El-Gorashi +2
In this paper, we propose the use of two Passive Optical Network (PON)-based network architectures to connect free-space Optical Wireless Communication (OWC) Access Points (APs) wi…
NOMA Visible Light Communication System with Angle Diversity Receivers
Mansourah K. Aljohani, Osama Zwaid Alsulami, Khulood D. Alazwary +4
In this paper, a non-orthogonal multiple access (NOMA) visible light communication (VLC) system is investigated. The system uses angle diversity receivers (ADRs) to provide high da…
Impact of user distribution on optical wireless systems
Khulood D. Alazwary, Osama Zwaid Alsulami, Sarah O. M. Saeed +4
In this paper, we investigate the impact of user distribution on resource allocation in visible light communication (VLC) systems, using a wavelength division multiple access (WDMA…
Data center top of rack switch to multiple spine switches optical wireless uplinks
Abrar S. Alhazmi, Osama Zwaid Alsulami, T. E. H. El-Gorashi +2
Infrared (IR) uplinks can achieve high data rates, which are essential in a range of applications. This paper introduces a novel approach to enable data centre uplink communication…
Resilience in Optical Wireless Systems
Sarah O. M. Saeed, Sanaa Hamid Mohamed, Osama Zwaid Alsulami +3
High reliability and availability of communication services is a key requirement that needs to be ensured by service providers. Since the direct line-of-sight (LOS) beam is prone t…
Beam Blockage in Optical Wireless Systems
Sarah O. M. Saeed, Sanaa Hamid Mohamed, Osama Zwaid Alsulami +3
In this paper, we use the percentage blockage as a metric when an opaque disc obstructs the Line-of-Sight link from the access point to the receiver in an optical wireless indoor c…
