Spatial Configuration of Agile Wireless Networks with Drone-BSs and User-in-the-loop

Irem Bor-Yaliniz, Amr El-Keyi, Halim Yanikomeroglu

Agile networking can reduce over-engineering, costs, and energy waste. Towards that end, it is vital to exploit all degrees of freedom of wireless networks efficiently, so that ser…

On Optimizing Cooperative Cognitive User Performance under Primary QoS Constraints

Adel M. Elmahdy, Amr El-Keyi, Tamer ElBatt +1

We study the problem of optimizing the performance of cognitive radio users with opportunistic real-time applications subject to primary users quality-of-service (QoS) constraints.…

On the Stable Throughput of Cooperative Cognitive Radio Networks with Finite Relaying Buffer

Adel M. Elmahdy, Amr El-Keyi, Tamer ElBatt +1

In this paper, we study the problem of cooperative communications in cognitive radio systems where the secondary user has limited relaying room for the overheard primary packets. M…

A Probabilistic MAC for Cognitive Radio Systems with Energy Harvesting Nodes

Ramy E. Ali, Fadel F. Digham, Karim G. Seddik +3

In this paper, we consider a cognitive radio (CR) system where the secondary user (SU) harvests energy from both the nature resources and the primary user (PU) radio frequency(RF)…

Energy-Efficient Cooperative Cognitive Relaying Schemes for Cognitive Radio Networks

Ahmed El Shafie, Tamer Khattab, Amr El-Keyi

We investigate a cognitive radio network in which a primary user (PU) may cooperate with a cognitive radio user (i.e., a secondary user (SU)) for transmissions of its data packets.…

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…
