Optimal Random Access and Random Spectrum Sensing for an Energy Harvesting Cognitive Radio
Ahmed El Shafie, Ahmed Sultan
We consider a secondary user with energy harvesting capability. We design access schemes for the secondary user which incorporate random spectrum sensing and random access, and whi…
Shapiro and parametric resonances in coupled Josephson junctions
Ma. A. Gaafar, Yu. M. Shukrinov, A. Foda
The effect of microwave irradiation on the phase dynamics of intrinsic Josephson junctions in high temperature superconductors is investigated. We compare the current-voltage chara…
Maximum Secondary Stable Throughput of a Cooperative Secondary Transmitter-Receiver Pair: Protocol Design and Stability Analysis
Ahmed El Shafie, Tamer Khattab, Amr El-Keyi +1
In this paper, we investigate the impact of cooperation between a secondary transmitter-receiver pair and a primary transmitter (PT) on the maximum stable throughput of the primary…
On the Diversity Gain Region of the Z-interference Channels
Mohamed S. Nafea, Karim G. Seddik, Mohammed Nafie +1
In this work, we analyze the diversity gain region (DGR) of the single-antenna Rayleigh fading Z-Interference channel (ZIC). More specifically, we characterize the achievable DGR o…
Distributed Cooperative Q-learning for Power Allocation in Cognitive Femtocell Networks
Hussein Saad, Amr Mohamed, Tamer ElBatt
In this paper, we propose a distributed reinforcement learning (RL) technique called distributed power control using Q-learning (DPC-Q) to manage the interference caused by the fem…
On the Role of Vehicular Mobility in Cooperative Content Caching
Osama Attia, Tamer ElBatt
In this paper, we analyze the performance of cooperative content caching in vehicular ad hoc networks (VANETs). In particular, we characterize, using analysis and simulations, the…
