Design and Implementation of Multi-Protocol Data Networks Interface Detector in Heterogeneous IoTs
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
In Internet of Everything (IoE) or heterogeneous IoTs, there exist a plethora of protocols and inter-connected Internet of Things. For every network protocol, the complexity of communication and wiring at the physical ...
Secure Performance Analysis for Full-Duplex Cooperative NOMA System in the Presence of Multiple Eavesdroppers
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
This paper investigates the physical layer security of a full-duplex (FD) Decode-and-Forward (DF) NOMA network assumed to undergo independent and identically distributed Nakagami-m fading. Herein, we provide a secrecy ...
Atmospheric turbulence effect on hybrid FSO/RF systems
(
IEEE Computer Society
, 2017 , Conference Paper)
This article is focused on the atmospheric turbulence attenuation and their effect on the hybrid free space optical and radio frequency (FSO/RF) under Qatar harsh and dry climate. Analysis has been done by calculating the ...
A smart rig for calibration of gas sensor nodes: Test and deployment
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
Nowadays, large number of sensors are deployed and used for air quality monitoring or in some industries that process hazardous gases. These sensors need periodic calibration to ensure reliable measurements. This paper ...
Secrecy Performance Analysis of Cooperative NOMA system with multiple DF Relays
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
In this paper, we derive the Secrecy Outage Probability (SOP) and Strictly Positive Secrecy Capacity (SPSC) of cooperative Non Orthogonal Multiple Access (NOMA) in the presence of K Decode and Forward (DF) relays and ...
Indoor test of the fog's effect on FSO link
(
SPIE
, 2017 , Conference Paper)
In order to distinguish the most rigorous model, we made a comparison between measurements data and the mostly used empirical models. These models use the visibility as a basic parameter to predict the fog attenuation. In ...
Power Generation Voting Prediction Model of Floating Photovoltaic System
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
Solar energy is the most promising renewable energy within the Gulf area as annual solar irradiance is among the highest in the world (>2000kWh/m2). Therefore, countries within the Gulf area have focused their energy ...
Preliminary studies on autonomous sensor systems dedicated to air quality monitoring
(
IMEKO-International Measurement Federation Secretariat
, 2014 , Conference Paper)
Sensor systems and smart networks devoted to environmental supervision have today assisted the analysis of primal processes and they have also provided vital hazard early warnings. At the same time the use of environmental ...
An experimental performance evaluation of the hybrid FSO/RF
(
SPIE
, 2017 , Conference Paper)
This paper is a first attempt to study the effects of atmospheric turbulences on hybrid free space optics/ radio frequency (FSO/RF) transmission system in Doha, Qatar. The state of Qatar is characterized by a Mediterranean ...
Feasibility of air quality monitoring systems based on environmental energy harvesting
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Capillary wireless sensor networks dedicated to air quality monitoring have provided essential information on hazardous air condition, generating early warnings to prevent danger situation for human health. The arising ...
