An Intelligent Resource Reservation for Crowdsourced Live Video Streaming Applications in Geo-Distributed Cloud Environment
Emna Baccour, Fatima Haouari, Aiman Erbad +4
Crowdsourced live video streaming (livecast) services such as Facebook Live, YouNow, Douyu and Twitch are gaining more momentum recently. Allocating the limited resources in a cost…
Proportionally Fair approach for Tor's Circuits Scheduling
Lamiaa Basyoni, Aiman Erbad, Amr Mohamed +2
The number of users adopting Tor to protect their online privacy is increasing rapidly. With a limited number of volunteered relays in the network, the number of clients' connectio…
DistPrivacy: Privacy-Aware Distributed Deep Neural Networks in IoT surveillance systems
Emna Baccour, Aiman Erbad, Amr Mohamed +2
With the emergence of smart cities, Internet of Things (IoT) devices as well as deep learning technologies have witnessed an increasing adoption. To support the requirements of suc…
Five-Layers SDP-Based Hierarchical Security Paradigm for Multi-access Edge Computing
Jaspreet Singh, Yahuza Bello, Ahmed Refaey +1
The rise in embedded and IoT device usage comes with an increase in LTE usage as well. About 70\% of an estimated 18 billion IoT devices will be using cellular LTE networks for eff…
Distributed interference management using Q-Learning in Cognitive Femtocell networks: New USRP-based Implementation
Medhat H. M. Elsayed, Amr Mohamed
Femtocell networks have become a promising solution in supporting high data rates for 5G systems, where cell densification is performed using the small femtocells. However, femtoce…
Energy-Aware Cooperative Wireless Networks with Multiple Cognitive Users
Mahmoud Ashour, M. Majid Butt, Amr Mohamed +2
In this paper, we study and analyze cooperative cognitive radio networks with arbitrary number of secondary users (SUs). Each SU is considered a prospective relay for the primary u…
DDSAT: Distributed Dynamic Spectrum Access Protocol Implementation Using GNURadio and USRP
Medhat H. M. Elsayed, Amr A. El-Sherif, Amr Mohamed
Frequency spectrum is one of the valuable resources in wireless communications. Using cognitive radio, spectrum efficiency will increase by making use of the spectrum holes. Dynami…
On Spectrum Sharing Between Energy Harvesting Cognitive Radio Users and Primary Users
Ahmed El Shafie, Mahmoud Ashour, Tamer Khattab +1
This paper investigates the maximum secondary throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. Th…
Cognitive Radio Networks with Probabilistic Relaying: Stable Throughput and Delay Tradeoffs
Mahmoud Ashour, Amr A. El-Sherif, Tamer ElBatt +1
In this paper, we study and analyze fundamental throughput and delay tradeoffs in cooperative multiple access for cognitive radio systems. We focus on the class of randomized coope…
Optimal Cooperative Cognitive Relaying and Spectrum Access for an Energy Harvesting Cognitive Radio: Reinforcement Learning Approach
Ahmed El Shafie, Tamer Khattab, Hussien Saad +1
In this paper, we consider a cognitive setting under the context of cooperative communications, where the cognitive radio (CR) user is assumed to be a self-organized relay for the…
Cooperative Access in Cognitive Radio Networks: Stable Throughput and Delay Tradeoffs
Mahmoud Ashour, Amr A. El-Sherif, Tamer ElBatt +1
In this paper, we study and analyze fundamental throughput-delay tradeoffs in cooperative multiple access for cognitive radio systems. We focus on the class of randomized cooperati…
