A hardware implementation for efficient spectrum access in cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Opportunistic spectrum access is a propitious technique to overcome the under-utilization of spectrum bands. In this work, we design an experimental test-bed for evaluating an un-slotted spectrum access scheme under real ...
A novel chaos-based physical layer security transmission scheme for internet of things
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
The Internet of Things (IoT) has attracted much attention in many fields, such as healthcare, transportation, finance and other critical infrastructures. But how to ensure the security of whole IoT system and the privacy ...
Impact of multiple video representations in live streaming: A cost, bandwidth, and QoE analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Video streaming is one of the most popular and highest bandwidth consumers within the Internet today. Cloud's elastic and pay-per-use model offers viable solution to varying demands of heterogeneous viewers for large-scale ...
Characterization of the indoor-outdoor radio propagation channel at 2.4 GHz
(
IEEE
, 2011 , Conference Paper)
We present the site-specific signal strength measurement results for path loss, shadowing, and fading in 2.4GHz band under typical harsh environment (high temperature 4050 C and humidity 8090%). We use spectrum analyzer ...
HARQ Performance over FSO Channels with Atmospheric Fading and Pointing Errors
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Free space optical communications (FSO) have witnessed a growing interest in the last few decades due to its various advantages. However, this technology suffers from its sensitivity to the atmospheric conditions such as ...
Smart Grid Cybersecurity: Standards and Technical Countermeasures
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Cybersecurity in smart grids is of critical importance given the heavy reliance of modern societies on electricity and the recent cyberattacks that resulted in blackouts. The evolution of the legacy electric grid to a ...
Computational thermodynamic analysis of solar fuel production via metal oxide based H2O and CO2 splitting thermochemical cycles
(
AIChE
, 2015 , Conference Paper)
In this paper thermodynamic feasibility of the production of solar fuel via SnO2/SnO based thermochemical CO2 splitting redox reactions was investigated. The first step is the thermal dissociation of SnO2 into SnO where ...
Iot-based fall and ecg monitoring system: Wireless communication system based firebase realtime database
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Monitoring elderlies living alone has been a rising issue that caregivers are interested in solving since many elderlies are at risk of experiencing a fall. In the absence of urgent help, serious consequences may occur. ...
A new web-based project and employee time tracking system for project management
(
EMCIS
, 2010 , Conference Paper)
Project and Time Tracking System (PTTS) is a web application that provides an automated and centralized method of tracking and monitoring work time for active projects by enabling supervisors to track employees work time, ...
Adaptive local search approach for the timetable scheduling problem
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
In this paper, we present a new Adaptive Local Search approach (ALS) and its implementation for the NP hard Timetable Scheduling Problem. This approach uses graph heuristics to generate the initial solution and the Aspiration ...
