Reinforcement learning-based decision support system for COVID-19
(
Elsevier
, 2021 , Article)
Globally, informed decision on the most effective set of restrictions for the containment of COVID-19 has been the subject of intense debates. There is a significant need for a structured dynamic framework to model and ...
On the coexistence of a primary user with an energy harvesting secondary user: A case of cognitive cooperation
(
John Wiley and Sons Ltd
, 2016 , Article)
In this paper, we consider a cognitive scenario where an energy harvesting secondary user shares the spectrum with a primary user. The secondary source helps the primary source in delivering its undelivered packets during ...
Performance of eigenvalue based spectrum sensing in full-duplex cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Spectrum sensing is a key component in any cognitive radio network. Recently full-duplex communication, i.e., the ability to transmit and receive at the same time at the same frequency, has become feasible. Residual self ...
A Survey on Mobile Crowd-Sensing and Its Applications in the IoT Era
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article Review)
Mobile crowd-sensing (MCS) is a new sensing paradigm that takes advantage of the extensive use of mobile phones that collect data efficiently and enable several significant applications. MCS paves the way to explore new ...
Secret communication on the Z-Channel with cooperative receivers
(
IEEE Computer Society
, 2017 , Conference Paper)
The discrete memoryless Z-Channel with a confidential message and a cooperative receiver (DM-ZC-CMCR) is considered. A noiseless one-sided rate-limited cooperation link exists between the two receivers. The secrecy level ...
On the Achievable Rates of OFDM with Common Phase Error Compensation in Phase Noise Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper considers the problem of analytically assessing the maximum achievable rates (capacity) of orthogonal frequency division multiplexing (OFDM) transmissions when the receiver, for complexity reasons, only accounts ...
Smart System to Monitor Social-Distancing During the Covid-19 Pandemic
(
Qatar University Press
, 2020 , Poster)
We introduce a smart system to track and maintain real-time physical distance between people and to warn people to any deviation from the prescribed distances. Social-distancing is an effective way of slowing infectious ...
On secure communication over the Z-Channel
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
The discrete memoryless Z-Channel (DM-ZC) with a confidential cross-message is considered. Three messages are transmitted; encoder 1 transmits one message to be decoded by decoder 1. Encoder 2 transmits two messages, the ...
Carrier Aggregation for Cooperative Cognitive Radio Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
The ever-increasing demand for mobile Internet and high-data-rate applications poses unique challenging requirements for 5G mobile networks, including spectrum limitations and massive connectivity. Cognitive radio and ...
Optimized Error Probability for Weighted Collaborative Spectrum Sensing in Time-and Energy-Limited Cognitive Radio Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
In this paper, a collaborative energy-harvesting cognitive radio (CR) network is considered such that the transmitter of the secondary user (SU) is allowed to harvest signal energy of the primary user (PU) when the presence ...
