no code implementations2 Apr 2024 Ahrar N. Hamad, Walter Zibusiso Ncube, Ahmad Adnan Qidan, Taisir E. H. El-Gorashi, Jaafar M. H. Elmirghani

Optical wireless communication (OWC) arises as a complementary technology to radio frequency (RF) systems that can support high aggregate data rates.

Multiuser beam steering OWC system based on NOMA

no code implementations10 Apr 2023 Y. Zeng, Sanaa H. Mohamed, Ahmad Qidan, Taisir E. H. El-Gorashi, Jaafar M. H. Elmirghani

We study the performance of the NOMA-based multiuser beam steering system in terms of the achievable rate and Bit Error Rate (BER).

Relay Assisted Multiuser OWC Systems under Human Blockage

no code implementations10 Apr 2023 Y. Zeng, Sanaa H. Mohamed, Ahmad Qidan, Taisir E. H. El-Gorashi, Jaafar M. H. Elmirghani

This paper proposes using cooperative communication based on optoelectronic (O-E-O) amplify-and-forward relay terminals to reduce the influence of the blockage and shadowing resulting from human movement in a beam steering Optical Wireless Communication (OWC) system.

Resource Allocation in IRS-aided Optical Wireless Communication Systems

no code implementations3 Apr 2023 Ahrar N. Hamad, Ahmad Adnan Qidan, Taisir E. H. El-Gorashi, Jaafar M. H. Elmirghani

One of the main challenges facing optical wireless communication (OWC) systems is service disconnection in high blockage probability scenarios where users might lose the line of sight (LoS) connection with their corresponding access points (APs).

Energy Efficient Placement of ML-Based Services in IoT Networks

no code implementations23 Mar 2022 Mohammed M. Alenazi, Barzan A. Yosuf, Sanaa H. Mohamed, Taisir E. H. El-Gorashi, Jaafar M. H. Elmirghani

The Internet of Things (IoT) is gaining momentum in its quest to bridge the gap between the physical and the digital world.

Reinforcement Learning for Resource Allocation in Steerable Laser-based Optical Wireless Systems

no code implementations21 Jun 2021 Abdelrahman S. Elgamal, Osama Z. Alsulami, Ahmad Adnan Qidan, Taisir E. H. El-Gorashi, Jaafar M. H. Elmirghani

Vertical Cavity Surface Emitting Lasers (VCSELs) have demonstrated suitability for data transmission in indoor optical wireless communication (OWC) systems due to the high modulation bandwidth and low manufacturing cost of these sources.
