Towards Mobility-Aware Proactive Caching for Vehicular Ad hoc Networks
Yousef AlNagar, Sameh Hosny, Amr A. El-Sherif
Harnessing information about the user mobility pattern and daily demand can enhance the network capability to improve the quality of experience (QoE) at Vehicular Ad-Hoc Networks (…
Cooperation and Underlay Mode Selection in Cognitive Radio Network
Ramy Amer, Amr A. El-Sherif, Hanaa Ebrahim +1
In this research, we proposes a new method for cooperation and underlay mode selection in cognitive radio networks. We characterize the maximum achievable throughput of our propose…
Cooperative Cognitive Radio Network with Energy Harvesting: Stability Analysis
Ramy Amer, Amr A. El-Sherif, Hanaa Ebrahim +1
This paper investigates the maximum stable throughput of a cooperative cognitive radio system with energy harvesting Primary User and Secondary User. Each PU and SU has a data queu…
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…
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…
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…
Adaptive Energy-aware Encoding for DWT-Based Wireless EEG Monitoring System
Ramy Hussein, Amr Mohamed
Wireless Electroencephalography (EEG) tele-monitoring systems performing encoding and streaming over energy-hungry wireless channels are limited in energy supply. However, excessiv…
A Soft Sensing-Based Cognitive Access Scheme Exploiting Primary Feedback
Ahmed M. Arafa, Karim G. Seddik, Ahmed K. Sultan +2
In this paper, we examine a cognitive spectrum access scheme in which secondary users exploit the primary feedback information. We consider an overlay secondary network employing a…
