Performance characterization of underwater visible light communication
Elamassie, Mohammed; Miramirkhani, Farshad; Uysal, Murat (IEEE, 2019-01)In this paper, we investigate the performance limits of underwater visible light communication (UVLC) systems. We first develop a closed-form path loss expression as a function of transceiver parameters and water type. We ... -
Performance characterization of vertical underwater VLC links in the presence of turbulence
Elamassie, Mohammed; Uysal, Murat (IEEE, 2018-09-24)In this paper, we investigate the performance of vertical underwater visible light communication (VLC) links. In vertical links, water properties such as temperature and salinity change with the depth. This leads to changes ... -
Practical electrical energy production to solve the shortage in electricity in Palestine and Pay Back period
Badawi, A. S. A.; Hasbullah, N. F.; Yusoff, S.; Hashim, A.; Elamassie, Mohammed (Institute of Advanced Engineering and Science, 2019)In this paper power energy had been estimated based on actual wind speed records in a coastal city in Palestine Ashdod. The main aims of this study to determine the feasibility of wind turbine and to estimate payback period. ... -
Resource allocation for downlink OFDMA in underwater visible light communications
Elamassie, Mohammed; Karbalayghareh, Mehdi; Miramirkhani, Farshad; Uysal, Murat; Abdallah, M.; Qaraqe, K. (IEEE, 2019-06)As a wireless connectivity solution with low latency and high capacity, visible light communication (VLC) is particularly attractive for high-speed underwater applications such as image or real-time video transmission. In ... -
SCARA with Path trajectory
The following Matlab project contains the source code and Matlab examples used for SCARA with Path trajectory. By defining the initial position and final position the robot will follow the path between these two points -
Spatial power spectrum of natural water turbulence with any average temperature, salinity concentration, and light wavelength
Yao, J. R.; Elamassie, Mohammed; Korotkova, O. (The Optical Society, 2020-10-01)The power spectrum of water optical turbulence is shown to vary with its average temperature < T > and average salinity concentration < S >, as well as with light wavelength lambda. This study explores such variations for ... -
Transmit laser selection for underwater visible light communication systems
Elamassie, Mohammed; Al-Nahhal, Mohamed; Kızılırmak, R. Ç.; Uysal, Murat (IEEE, 2019)Visible light communication (VLC) has the potential to serve as a high-speed underwater wireless connectivity solution to support real-time image and video transmission. Underwater propagation medium imposes additional ... -
Underwater visible light communications in cascaded gamma-gamma turbulence
Elamassie, Mohammed; Sait, S. M.; Uysal, Murat (IEEE, 2018)In this paper, we investigate the performance of vertical underwater visible light communication (VLC) links in the presence of moderate and strong turbulence conditions using Gamma-Gamma (GG) probability density function. ... -
Vehicle-to-infrastructure visible light communications: Channel modelling and capacity calculations
Eldeeb, Hossıen Badr; Elamassie, Mohammed; Uysal, Murat (IEEE, 2020)In this paper, we investigate the performance of a visible light communication (VLC) system for vehicle-to-infrastructure (V2I) connectivity. Two headlamps of the vehicle serve as wireless transmitters while photodetectors ... -
Vehicular VLC channel model for a low-beam headlight transmitter
Mohamed, Bassam Aly Abdelrahman; Elamassie, Mohammed; Uysal, Murat (IEEE, 2021-09-06)The availability of LED-based headlights and taillights allows visible light communication (VLC) to be considered as a powerful wireless access technology for vehicle-to-vehicle (V2V) communications. A crucial system design ... -
Vertical underwater visible light communication links: Channel modeling and performance analysis
Elamassie, Mohammed; Uysal, Murat (IEEE, 2020-10)Underwater visible light communication (UVLC) has been introduced to support emerging high data rate applications such as real-time image and video transmission. Initial works on UVLC build upon the assumption of fixed ... -
Vertical underwater VLC links over cascaded gamma-gamma turbulence channels with pointing errors
Elamassie, Mohammed; Uysal, Murat (IEEE, 2019)Underwater visible light communication (UVLC) is a high capacity wireless connectivity solution with low latency, particularly appealing for real-time underwater video and image transmission. While attenuation and geometrical ...
