DMT analysis and optimal scheduling for two-hop parallel relay networks
(Elsevier, 2021-06)
Two-hop parallel networks with half-duplex relays over quasi-static Rayleigh fading channels are considered. Assuming relays have only local channel state information, optimal communication schemes for these networks in ...
Characterization of LEDs for visible-light communications
(SPIE, 2021-02)
Recent advances in solid-state technologies have enabled the development of light-emitting diodes (LEDs) with favorable features such as long life expectancy, low-power consumption, and reduced heat dissipation. Visible-light ...
Effect of scattering phase function on underwater visible light communication channel models
(Elsevier, 2021-10)
Non-sequential ray tracing simulations are commonly employed to model underwater visible light communication (VLC) channels. The accuracy of such simulations highly depends on how well the optical properties of water (i.e., ...
Capacity analysis of NOMA-enabled underwater VLC networks
(IEEE, 2021)
Visible light communication (VLC) has recently emerged as an enabling technology for high capacity underwater wireless sensor networks. Non-orthogonal multiple access (NOMA) has been also proven capable of handling a massive ...
Hybrid RF/VLC systems: A comprehensive survey on network topologies, performance analyses, applications, and future directions
(IEEE, 2021)
Wireless communications refer to data transmissions in unguided propagation media through the use of wireless carriers such as radio frequency (RF) and visible light (VL) waves. The rising demand for high data rates, ...
UAV-assisted free space optical communication system with amplify-and-forward relaying
(IEEE, 2021-09)
In this paper, the performance of an unmanned aerial vehicle (UAV)-based free-space optical relay system with amplify-and-forward relaying is analyzed. In particular, the statistical probability of end-to-end signal-to-noise ...
Composite fading model for aerial MIMO FSO links in the presence of atmospheric turbulence and pointing errors
(IEEE, 2021-06)
In this letter, we introduce accurate approximation expressions for composite fading channel model and outage probability of multiple-input multiple-output (MIMO) free space optical (FSO) link between two unmanned aerial ...
Wi-Fi assisted two-hop relay probing in WiGig device to device networks
(IEEE, 2021-06)
Relaying is a key technology for millimeter wave communications to extend the range and to route around blockages. In practical implementation of relaying systems, probing is required to identify proper neighbor terminals ...
AUV trajectory optimization for an optical underwater sensor network in the presence of ocean currents
(IEEE, 2021)
Autonomous underwater vehicles (AUVs) are instrumental for data offloading in underwater sensor networks (USNs). With high data rate capacity at transmission ranges in the order of several tens of meters, visible light ...
Analysis and optimization of the network throughput in IEEE 802.15.13 based visible light communication networks
(IEEE, 2021)
In line with the growing interest on visible light communication (VLC), IEEE has initiated standardization efforts on this emerging technology. In this work, we consider IEEE 802.15.13 Optical Wireless Personal Area Networks ...
