Optimal Spectrum Access for a Rechargeable Cognitive Radio User Based on Energy Buffer State
Ahmed El Shafie, Mahmoud Ashour, Amr Mohamed +1
This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maint…
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…
Power-Optimal Feedback-Based Random Spectrum Access for an Energy Harvesting Cognitive User
Mahmoud Ashour, Ahmed El Shafie, Amr Mohamed +1
In this paper, we study and analyze cognitive radio networks in which secondary users (SUs) are equipped with Energy Harvesting (EH) capability. We design a random spectrum sensing…
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…
