Improved Spectrum Mobility using Virtual Reservation in Collaborative Cognitive Radio Networks
Ayman T. Abdel-Hamid, Ahmed H. Zahran, Tamer ElBatt
Cognitive radio technology would enable a set of secondary users (SU) to opportunistically use the spectrum licensed to a primary user (PU). On the appearance of this PU on a speci…
Coverage Probability Analysis for Wireless Networks Using Repulsive Point Processes
Abdelrahman M. Ibrahim, Tamer ElBatt, Amr El-Keyi
The recent witnessed evolution of cellular networks from a carefully planned deployment to more irregular, heterogeneous deployments of Macro, Pico and Femto-BSs motivates new anal…
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…
